Easychem Coli Online

EASYCHEM COLI online is an analyzer that automates the Colilert®-18 analytical method for determining coliforms in drinking water, surface water, wastewater, and bathing water.

EASYCHEM COLI online simultaneously detects both total coliforms (TC) and Escherichia coli (EC) in water, and/or fecal coliforms (FC); Measurement results, using the Presence/Absence (P/A), Time To Detect (TTD), and Multiple Tube Fermentation (MTF) techniques, are produced within 18 hours, depending on the measurement range.

The Colilert®-18 medium is recognized as an international standard (ISO) 9308-2:2012 and is also approved by the EPA and APPHA (Standard Methods for the Examination of Water and Wastewater).

DETECTABLE BACTERIA

TOTAL coliforms, by colorimetric method
E. coli, by fluorimetry
FECAL coliforms, colorimetric.

Total Coliforms+E. coli Incubated at 35 – 37 ±0.5 °C Faecal Coliforms incubated at 44.5 ±0.5 °C. Other measurable bacterial strains on request (Enterococci, HPC).

Robust and reliable

Designed for industrial and environmental online applications, it ensures the highest degree of robustness in electronic, mechanical, and hydraulic components.

Easy to install

The analyser is delivered after successful factory testing. It is supplied ready for installation, complete with the parts necessary for its field start-up.

STATISTICAL ASSESSMENT OF CONTAMINATION

The analyser allows the detection of coliform contamination by means of Presence/Absence testing.Per annum) (TC e EC o Football Club), which can be combined with the quantitative “Multiple Tube Fermentation” method (MTF) 35-37 °CTC e EC) or 44.5 °C (Football Club), with an analytical frequency configurable according to user requirements. At the same time, a first-alert semi-quantitative estimate of coliform contamination can be made using the “detection time” technique.TTDfor the TC Each other Football Club.

Advantages and benefits

Fully automated analysis
28 days of autonomy, one sample a day, with automatic detection of total coliforms, E. coli and faecal coliforms, or 56 samples with automatic detection of total coliforms and E. coli or, alternatively, faecal coliforms
The use of standard 100 mL single-use bottles ensures that the sample is representative and prevents contamination
It does not require long washes or the use of cleaning solutions.
Automatic generation of local and remote alarms via Ethernet or optional GSM/GPRS/3G remote connection
Annual maintenance.
