Portable Water Quality Test Kit, Basic Bacteriological Field test kit 1. This essentially Emergency Kit contains a Single incubator, Pool Tester and a Conductivity meter for on-site basic water quality assessment in the Field, including DPD/pH tablets and consumables for 200-250 tests.
This type of lightweight, portable and easy to use kit for has originally been designed by the University of Surrey in collaboration with OXFAM to test water quality primarily for Microbiological contamination and to determine its safety for human consumption. It is especially useful in emergency situations where testing and results can be determined quickly so that corrective action may be taken without delay.
This Basic Water quality testing kit is also called "Portable Bacteriological Field test kit 1" with type equivalency to e.g. the Delagua Basic and the Wagtech Potatest kits.
The Portable Field Water Quality Test Kit, for basic water quality assessment in the Field, including Microbiological Testing, pH, Chlorine and Turbidity measuring on-site in the Lab or in the Field at the source, is integrated in a carrying case, and composed as follows:
Portable Single Compartment Incubator for analysis of Faecal Coliforms at 44°C (± 0.5ºC). Alternatively, it can be easily switched or calibrated to 37°C for Total Coliform Count.
The incubator compartment can accommodate approximately between 16 and 25 slim fit Aluminum Petri dishes (minimum 16), supplied with a total of around 50 re-useable Aluminium Petri Dishes which are as standard in Petri Dish Racks or equivalent for easy compartment loading.
The temperatures are displayed on a LCD with an indication for low battery. The incubator has a timer facility that logs the incubation period in case of power failure.
The incubator can be run from internal rechargeable battery,
110/220 V mains or 12 V DC supply such as vehicle battery/ Dash-board Cigarette lighter. The Battery may be separate from the incubator for easy replacement, but to be stored inside the carrying case
If the mains supply fails the internal battery automatically switches on. Supplied with all necessary electrical leads & crocodile dips etc.
The battery shall allow for minimum 5 incubation cycles, and be fully rechargeable within one day.
The Incubator kit includes a membrane filtration unit using 0.45 um pore size membrane filter (as appropriate complete with Collection Flask, Sampling Cup and Land Line plus Bronze Discs, Gaskets and O-Rings, as well as a Vacuum Pump preferably with pistol grip, etc.), a set of accessories for the proper handling of the tests such as a pad dispenser, tweezers, dropping pipettes, plastic bottles, hand lens, lighter, pen, screwdriver, lubrication grease, a spirit thermometer (-10 to +50ºC x 0.5ºC) etc., and an Incubator calibration kit, including calibration dishes.
Sterilisation is possible with methanol (methanol not included).
The incubator is supplied with sufficient membranes, pads and media to carry out 200 tests (see below).
The portable kit also includes following testing equipment:
- Turbidity measurement tube (2 or 3 parts) range minimum 5-1000 NTU. Simple to use graduated plastic tube for measuring turbidity of water. High grade material for prolonged use.
CHLORINE AND PH:
- Visual Comparator of simple Pool-tester/block type for testing pH, Free and Total Chlorine, in drinking water.
Supplied with Deionised water pack for potential sample dilutions. Complete with reagents for 250 tests each of pH, Free and Total Chlorine.
CONDUCTIVITY (and pH):
Digital, Conductivity / TDS (Total Dissolved Solids) Meter with automatic temperature compensation (ATC) and internal calibration.
Range (0 to 9990 uS/cm minimum). Resolution 0.1, 1 uS/cm, 0.01 mS/cm or equivalent. Accuracy ±1 % full scale or better.
Operating temperature (0 to 50ºC minimum).
The Conductivity meter may be supplied as a combined multi parameter instrument, including pH measuring, as (EC/pH/mV/°C) Meter, buffer calibrated (pH 4, 7, and 10), with ATC. Range (pH 0 to 14 minimum). Accuracy ±0.1 pH unit. Supplied with a pH / Temperature probe.
NOTE: The Digital, battery operated meter is of portable, light weight and compact hand held types. It is waterproof to IP67, having a large display, and if compact Tester type with integrated but replaceable cup type sensors. The Meter is supplied with all relevant buffer/calibration solutions/standards, etc. as appropriate.
(NB: If digital pH metering is supplied within the kit, though Phenol Red tablets will be supplied initially with the pool/block tester, these will not be required in further refill supplies, unless desired by end user.)
CONSUMABLES AND REAGENTS INCLUDED WITH THE KIT
- The Incubator is supplied with Consumables for at least 200 Microbiological tests (Gridded Membrane filters and growth Pads, Pad dispenser and culture medium 38.1g Membrane Lauryl Sulphate Broth tube).
- The Block/Pool Comparator is supplied with DPD No 1, DPD No 3 and Phenol Red tablets
- The Digital Meter is supplied with relevant electrodes/sensors, buffer and calibration solutions/standards, etc. as appropriate.
All comes complete with full Operating Instructions and Water Quality Report Sheets within the kit. Languages will be in English/French and as appropriate for the receiving countries.
All the above laboratory components are housed in a protective, robust, rigid, durable, lightweight, hinged and lockable Polypropylene (or equivalent sturdy e.g. Aluminum material) Carrying Case with handle. The case shall be conceived with water proof materials and to be water proof when positioned normally on a wet ground.
If required, the following items should be ordered separately:
Additional consumables for future use
Estimated weight: 12kg
Estimated volume: 61.2 CDM
Instructions for use
The following items which are not included in the package must be provided to start the microbiological tests:
Pressure cooker or portable sterilizer or access to an autoclave (e.g. in a nearby hospital or laboratory).
Methanol (at least 1-2 ml. per test)
Measuring cylinder or a beaker
This kit can be used for surveillance and monitoring of water quality at the source, in water storage tanks, in treatment plants, at the consumer level etc. It does not test for heavy metals such as arsenic, chromium, lead, mercury, nickel, or pesticides, insecticides, detergents, organic pollutants, phosphate, sulphate, cyanide, ammonia, radioactivity.
Precondition for utilisation:
Only for use by trained staff
Needs static dedicated room for use (not mobile when in use) with limited access and minimal external contamination
Requires adequate complimentary consumables
NOTE: Battery needs charging on monthly basis, if not in use
Complementary Requirements to be ordered separately:
The following items are needed to start the bacteriological tests:
Pressure cooker or portable sterilizer or access to an autoclave (e.g. in a nearby hospital or laboratory)
Methanol (at least one Ml/test)
1 litre measuring cylinder or a beaker
Membrane filters and pads for 1000 tests.
S0000550/-555 - Free Chlorine test, DPD No 1, 250 Tab. /Pack.
S0000551/-559 - Combined Chlorine test, DPD No. 3, 250 Tab. /Pack.
S0000552 - Total Chlorine test, DPD No.4, 250 Tab. /Pack
Additional incubator set at 37°C for the Total Coliform Count in water
Useful in all emergencies with drinking water contamination (biological)
Primary use in monitoring water quality and assisting in identification of sources of water contamination
Context in which item is mainly used:
Central (static) water testing lab, to which samples are brought for analysis.
Ranges from household water storage to urban bulk water system.
Emergency scenarios where the item should not be used:
Given that use requires static placement of the unit by trained personnel, deployment is limited to matching circumstances. Time from water to testing point is critical as is collection and handling of sample, suggesting use where some systems and infrastructure exists
Also, this kit does not test for heavy metals such as arsenic, chromium, lead, mercury, nickel, or pesticides, insecticides, detergents, organic pollutants, phosphate, sulphate, cyanide, ammonia, radioactivity.
Emergency scenarios: Time between sampling and testing plus stability of incubation must be adequately managed.
Transparency of activities occasionally sensitive
Samples en-route to testing need to be kept at appropriate temperature Voltage and access to power supply
