The COSA 707 is an easy to hold, hand-held emissions analyzers capable of measuring up to seven different gases. The emissions analyzer can be equipped with up to 6 electrochemical sensors and a CO2 IR-bench for simultaneous measurements. Cells can be installed for making measurements of low CO and low NO down to 0.1ppm. The COSA 707 has a bright 3.5" TFT display with backlights and a zoom function. The unit can communicate through Bluetooth, USB or with a 2GB SD-Card. New sensors for the COSA 707 include a CO2 sensor for a range of 0-20% (IR-Bench) and a H2S sensor for 0-500ppm (EC Sensor).
