Holroyd Components offers a variety of temperature controllers for sale online, including capillary, analogue and digital options, which are a great addition for accurate close temperature control. These can either be mounted directly on the heater or fitted in-line. The capillary thermostats have a fixed temperate range e.g. 0-120°C, whilst the digital option can be programmed for a bespoke range.
