What are Temperature Controllers?

Friday May 11 2018

Temperature controllers are among the most common forms of laboratory instrumentation, with near-limitless potential for supporting experiments in various fields of research. Their primary function is to monitor the thermal conditions of samples and to maintain levels within pre-defined or dynamic temperature parameters. This process often requires integration with multiple forms of equipment, such as thermocouple sensors that attach a temperature controller to an external heating or cooling element.

Several levels of laboratory instrumentation are broadly categorized under the term temperature controls, including dial-operated manual controls and intuitive precision temperature controllers. Each of these is equipped to perform thermal monitoring processes to different prioritized factors.

This article will explore some of the temperature controller options currently available in more detail:

Manual Temperature Controllers

A manual temperature control is usually compact and robust, boasting a comparatively small footprint to more advanced controls. Resistive load samples are commonly measured using manual temperature controllers, due to the easy regulation of input voltages using a simple interface of dials. The heat of the sample is directly correlative to the input voltages, allowing researchers to control temperatures accordingly.


While manual temperature controllers are rarely suitable for applications where minute degrees of accuracy for multiple processes are concerned, the cost efficiency of manual thermal controls is second to none.

Glas-Col offers a broad range of manual temperature controllers, including timed units that run output voltages of up to 240 V in repetitive cycles.

Basic Temperature Controllers

Basic temperature controls introduce a level of automation to the temperature control process without exorbitantly increasing the cost of devices. These instruments are equipped with thermocouple inputs to enable automatic temperature regulation to pre-determined parameters. The immediate advantage of these controllers is the accurate acquisition of thermal data as opposed to a calculated measurement based on input voltage.

Basic temperature controllers are suitable to a broad range of applications, reducing the necessity for experiment micro-management. However, they are not typically recommended for temperature critical processes.

Glas-Col carries an established range of basic temperature controls and accessories for assembling bespoke control systems in-house.

Precision Temperature Controllers

Precision temperature controls offer ultimate control accuracy due to user-friendly digital displays and sensitive thermal sensors capable of monitoring temperatures to within +/-1.0°C. These feature auto-displays of temperature setpoints and processes to enable automated temperature control with exceptional degrees of precision.

Precision controls set the benchmark for modern temperature controllers, providing unparalleled levels of accuracy and simple usability. Naturally, they are also the most expensive option.

Glas-Col provides a thorough range of precision temperature controllers to different specifications, including multiple displays and control outputs.
