Wall Mounted Tritium in Room Air Monitor

Model 607C-0.8U0.8CI

Applications

607C-0.8U0.8CI – Sensetecz Engineering Tritium in Air Monitor (hereinafter referred as 607C) is a 19” rack mount type instrument. It is customized from default 607 model.

607C-0.8U0.8CI has all characteristics of default 607 except its customized sensitivity and measuring range. Please refer to the model 607 datasheet for its default characteristics.

The customizations of 607C-0.8U0.8CI are as below: 

• Sensitivity: 0.8µCi/m³
• Measuring range: 0.8µCi/m³ to 0.8Ci/m³.
• 8µCi/m³ to 0.8Ci/m³ is defined as the full measuring range for all characteristic for 607C-0.8U0.8CI, i.e. Full measuring range noble gas compensation, full measuring range gamma compensation, etc.
