PPM offers PPB monitoring

Pollution and Process Monitoring's trace level TOC analysers are for applications requiring parts per billion measurement of ultra-pure water.

All the instruments in the PROTOC Trace Level (TL) range offer continuous, on-line monitoring in the range of 0-500ppb with a resolution of 5ppb up to 0-5ppm.

The PROTOC 100TL analyser offers single-stream monitoring with 4-20mA high and low alarm outputs. The typical response time is two or three mins.

The PROTOC 200TL offers the same features with the added benefit of auto-calibration and trend graphics on a large liquid crystal display.

For multi-channel monitoring, the PROTOC TL is fully programmable and capable of multiplexing up to six streams, while offering full autocalibration. The response time is also two minutes.

Larger applications may require multi-point monitoring and the PROTOC SPYDER TL and WEB system offers a powerful solution, in which one SPYDER unit can control and monitor up to eight WEB analyser units from a central control point. The SPYDER can be interfaced with a PC or on-site SCADA system.
