Overview
The 5235 TECSource is a popular temperature controller for lower power applications. With 24W of TEC control power and support for thermistor sensors (10µ or 100µ bias current), it’s still a powerful unit, but a good choice when the higher power or sensor support of the 5305 or 5310 is not needed. Housed in a compact enclosure, and supporting many of the same features as the larger 5300 family, the 5235 is an excellent mix of features, size, and price.

Excellent Stability
The 5235 offers excellent short term and long term stability. At less than 0.004°C stability over one hour, and 0.01°C over 24 hours, the 5235 provides an excellent solution for precision temperature control.

Fully Adjustable PID
The 5235 comes with eight factory set gain settings for the temperature control loop, which are sufficient for most applications, but also offers fully adjustable PID settings, allowing you to fine tune the response ogf the instrument. Also, because the loop is digital and uses the temperature (not sensor resistance) as the control variable, variations in sensor sensitivity across temperature (primarily seen with thermistors) does not affect the unit as it does with analog-based PID loops.
