TN 900TC

 

TN900 is an ultra-fine digital thermometer-regulator for use with S-type thermocouple.

§    The regulation component of this instrument (with PID function) allows to stabilize the temperature at the desired set-point within 0.01°C (in liquids). PID parameters and set-point can be set manually (with keys) or remotely (via RS232). Set-point resolution of 0.01°C (over the range 0 to 1,500°C) is as fine as the resolution of the measurement component.

§    The measurement component of this instrument is composed of a highly precise thermometer (TN850) which stability supports this exceptional regulation performance.
