1.Compact Turbimeter

Turbidity and Total Suspended Solids (TSS) are two of the most important indicator parameters for drinking water quality, natural/surface water management and wastewater treatment. The Compact Turbimeter uses unique QuadoptiX™ technology to provide:
• Maximum reliability and accuracy in the field
• Variety of operating/reading modes including Total Suspended Solids
• Full data log including time, date, Operator ID, Sample ID and calibration record for GLP compliance.
Operating according to the ISO 7027 standard, the Compact Turbimeter is ideal for the following applications:
Drinking Water - with a high sensitivity and high resolution of 0.01 NTU in the 0 – 1 NTU range, the Compact Turbimeter provides superb validation of drinking water quality and provides an essential tool for process control and management of drinking water production.
Natural/Surface Waters - with a wide dynamic range from 0 – 1050 NTU the Compact Turbimeter provides robust and reliable measurement of surface water turbidity and suspended solids for environmental studies.
Wastewater – utilising compensated turbidity measurement to give maximum resolution in wastewater and true ISO 7027 compliance, the Compact Turbimeter offers a Total Suspended Solids calibration option and continuous measurement mode for settling samples.
Available as a hard case portable kit and supported by SDVB calibration standards, the Compact Turbimeter guarantees ergonomic and accurate field measurement for turbidity and Total Suspended Solids.

2.Contour Comparator

The new Contour Comparator offers an excellent solution to visual testing requirements. Features include:
- Compact size with grip feature for ease of handling
- Discrete colour disc for definite results
- Single and dual parameter kits including reagents and accessories
The Contour Comparator is suitable for professional and occasional use. The unique contoured rear of the comparator is designed for comfort and grip in even the most challenging environment.

3. Potalab®: Advanced Long-Term Monitoring Kit (Physico-Chemical + Microbiological)

The Potalab® is a portable microbiological and physico-chemical water quality testing laboratory. It provides bacteriological testing using the accepted method of membrane filtration and incubation of faecal and total coliforms as an indicator of the presence of other harmful bacteria and viruses. The physico-chemical instruments are used in combination to quickly examine a supply to determine if a more detailed microbiological examination is required.
All equipment is easily packed within the aluminium case for complete portability.
For combined microbiological, physico-chemical testing in the lab or field Wide range of physico-chemical parameters can be measured using highly accurate digital instruments More cost effective than central laboratory testing Simple technique – dual incubator allows analysis of both faecal & total coliforms simultaneously Results incubated in just 14 hours Completely portable – even runs off solar power Uses low cost, long-life consumables, and equipment is easily sterilised in the field Supplied with reagents for Ammonia, Arsenic, Chlorine, Fluorides, Nitrites and Nitrates as standard. Other parameters available on request
Conforms to WHO Guidelines

4. Potatest®: Emergency Rapid Response Kit (Physico-Chemical + Microbiological)

Widely used by the humanitarian organisations involved in the immediate aftermath of natural disasters, large scale emergencies or refugee camps, where simple, low-cost, rapid response testing of the basic water quality parameters is essential to determine the safety of the water supply.
Total & Faecal Coliforms/pH/Turbidity/Free Chlorine Residual. For the combined testing of microbiological and physico-chemical water quality parameters Single incubator, lightweight polymer construction, with a capacity of 18 petri dishes Temperature switchable between 37 and 44ºC, allows incubation of either faecal or total coliforms Fully portable – can be powered via external rechargeable battery, AC mains operation, DC operation via vehicle lighter socket or even solar power Separate instruments to measure pH and Chlorine Highly accurate, waterproof, digital pocket meter for pH Colour Comparator with disc and reagents for 250 tests of free and total Chlorine Flexible chemical testing options – comparator allows further testing of over 30 chemical parameters if required Special pricing available for NGOs/Aid Agencies Uses, long-life, low-cost reagents and consumables available locally through Wagtech in-country representatives Supplied with reagents & consumables to carry out 200 micro-biological tests Comprehensive but simple to use operation manuals for all instruments All components housed in a single, lockable, water-proof plastic carry case

5. Potakit - Intermediate Low-Budget Testing Kit (Physico-Chemical + Microbiological)

The kit of choice for NGO's and water technicians implementing rural water and sanitation programmes and who only have access to limited funds but still wish to conduct an accurate assessment of the full range of drinking water quality parameters in the field.
This kit is capable of carrying out all the same tests as the Potalab, however the Potakit features less sophisticated instrumentation which in many cases makes the Potakit a more attractive and cost-effective choice.
