Chlorine Monitor

The Q46H Chlorine Monitor is an upgraded version of the Q45H system for continuous monitoring of free or combined chlorine. The system uses a polaro-graphic membraned sensor to measure chlorine directly, without the need for chemical reagents. When needed, automatic pH compensation may be added for free chlorine measurement accuracy. Systems are available to provide 4-20 mA outputs for chlorine, pH, and temperature. The Q46H system is economical to purchase and maintain. — Analytical Technology Inc., 800/959-0299, www.analyticaltechnology.com

The PGD2 can also be supplied with an oxygen sensor and up to two electrochemical sensors for various toxic gases. The instrument has audio/visual alarms and data logging capability, is ATEX certified and CE approved. — ENMET Corporation, 734/761-1270, www.enmet.com Circle 35 on Card

The Air Sampling Pump That Does More

The GilAir Plus has the widest dynamic flow range of any personal air sampling pump, and it is the first to offer QuadModeSM air sampling technology that enables constant flow of 20-5,000 cc’s per minute and constant pressure sampling in low and high flow modes without using external adaptors. It offers standard temperature and pressure correction, datalogging, programmabili-ty, a real-time clock, and selectable automatic fault recovery. GilAir Plus has an ergonomic design 1/3 smaller than traditional air sampling pumps, weighs less than 21 ounces, and offers multiple language capabilities. — Sensidyne LP, 727/530-3602, www.GilAirPlus.com Circle 36 on Card
