Checking for the presence of coliform in water is one of the most important water monitor parameters to ensure water quality standards are met. However, that was the only water quality parameter that was not available for fast automated (online) measurement - until now!
VWM's ColiMinder® is a fast, ultrasensitive and fully automated measurement system to detect viable bacteria in water. It is based on the measurement of specific enzymatic activity in target microorganisms using an optimized biochemical protocol and patented fluorescence photometric techniques. Able to perform up to 84 tests per day, it can detect very dynamic contamination patterns.
The ColiMinder® is suitable for long-term monitoring of bio-contaminated water samples to use in applications subject to tough environmental conditions.
How It Works?
The ColiMinder® takes 15 min measurement time followed by a 9 min cleaning cycle. You can choose to work in continuous or interval mode. With the continuous mode, you are able to perform up to 56 measurements per day. However, for a short time, measurement frequency can be increased to approx. 84 measurements per day (without cleaning). In interval mode you can manually set the time between the measurements. Also, when you use the interval mode, you can alternate between samples.
How Can I see My Data?
Connectivity is a big factor for the ColiMinder®. The device stores all your measurement data locally, but you are able to view and store your data in many ways. Measurement results are can be:
Available through RS232/RS485 or Modbus TCP
Directly transmitted to a server (requires LAN or WLAN connection)
Exported from the server in Excel or CSV format
Copied on to USB flash memory stick
Streaming data and measurement results can also be analysed on server-side using ColiMinder® visualization tools.
In addition to these features, an automatic warning notification (per E-mail or SMS) can be configured and all functions and programming can be performed through remote control (internet or network connection required. The ColiMinder® is able to control ISCO 6700 auto samplers, which also can be controlled remotely through ColiMinder® remote control.

Reagents and Consumables
There are two component measurement reagents (CM Quick Detect) you can use, a cleaning solution (CM Quick Clean) and rinsing water (not provided). Also, with the ColiMinder® no contaminated or hazardous waste is produced.
Reagents are suitable for applications in fresh water. Saline water reagents also available upon request. Reagents holding capacity is up to 1200 measurements.
Reagents available for the following target organisms:
- Fecal Contamination: E. coli (Beta-Glucuronidase Activity) - Coliform Bacteria (Beta-Galactosidase Activity) - Total Bacteria (ALP – Alkaline Phosphatase Activity)
Surface Water Monitoring, Drinking Water Monitoring, Flocculation Process Monitoring, Filtration Process Monitoring, Waste Water Treatment Plants Discharge Monitoring, Fruit Washing Water Monitoring, and many more!
Be sure to read this App note from Vienna Water Monitoring - ColiMinder Driving Lab - regarding the installation of a ColiMinder in a car, where samples are taken driving from sampling point to sampling point.

POA means "Price On Application". Items displaying POA instead of the sell price do so for a number of reasons, not least because we anticipate some additional information is required in order to supply the most suitable options/configuration to each individual customer.
