Using Michell’s latest generation of polymer moisture sensor to provide fast, reliable readings of dew-point, allowing for fast action to be taken by operators. The transmitter itself has a heavy duty M12 electrical connector and is calibrated to measure within the range of -60 to +60°C dew point: wide enough to cope with extreme conditions found in railways around the world. The sensor has the following rail-industry approvals: EMC/RFI approval to rail standard EN50121-3-2 Shock/vibration approved to rail standard IEC16373:1999-01 (EN50155)...

The next generation Advanced Quartz Crystal Microbalance analyzer from Michell Instruments is designed to provide reliable, fast and accurate measurement of trace moisture content in a variety of applications where keeping moisture to a minimum is of critical importance. The analyzer provides consistently accurate measurements of trace moisture. This consistency is achieved using a self-calibration system, which adjusts the sensor with reference to an internal moisture generator. The moisture generator is supplied with a calibration traceable to NPL and NIST, so long term stability of its measurements is guaranteed....

A simple and efficient, self-contained dew-point hygrometer, with filtration and flow control, for measurement of dew point or moisture content at point of use. It uses the Easidew On-Line to measure dew point in the range –100 to + 20 °C dew point, or moisture content in the range 0-3000 ppm. This well-proven instrument uses the Michell Ceramic Metal-Oxide Moisture Sensor providing accurate and stable measurements. It is part of our service exchange program for simple, cost-effective maintenance....

A lightweight oxygen analyzer or transmitter for cost-effective quality control in safe area applications, such as monitoring oxygen purity. Using Michell’s tried and tested Thermo-Paramagnetic oxygen sensing technology the XTP501 has no consumable parts to replace and offers users an extremely low cost of ownership due to minimal maintenance needs....

This small transmitter is a rugged, self-contained hygrometer for the measurement of trace moisture content in ultra-high purity gases. Simple to use and install, the Pura is available in 2-wire, 3-wire and hazardous area versions and is fully configurable to meet specific needs....

The XGA301 Industrial gas analyzer from Michell Instruments provides a convenient platform to measure oxygen, dew point, CO2 and CH4. The analyzer can be supplied in one of two bench-mounted chassis and with up to three sensors fitted. Standard features include two fully-programmable alarm circuits (voltage-free contacts), programmable analog outputs, RS232 communications and complete Windows-based data-logging software. The industrial zirconia oxygen sensor provides fast and accurate oxygen analysis over the range of 1 ppm to 30%* O2 and delivers stable and repeatable readings, with a typical response time of less than 5 seconds for a 90% response to a step change in gas compositions. The zirconia sensor is heated, and temperature-controlled to enable oxygen ions to conduct. An internal pressure sensor compensates for small changes in the gas pressure to maintain accurate and stable readings. An optional, variable speed-pump draws a gas sample at a flow rate set by the user between 0 to 1.2 Nl/min. The Easidew Sensor is available for dew points down to –100°C in combination with another sensor within the XGA301A2’s chassis. *Analyzer is not suitable for enriched oxygen...
