Matsuo Precision Thermostats

Matsuo thermostats are superior twin bimetal, electro-mechanical temperature controls offering precision thermal control.  These precision bimetal thermostats have a unique internal structure that offers a combination of tolerance, differential and repeatability that is un-paralleled in the industry.  The twin bimetal system minimises calibration drift and ensures a long contact life from 100,000 cycles to 1 million cycles depending on the applied load.

Matsuo thermostats offer excellent thermal protection and are ideal as anti-condensation thermostats, anti-freeze controls or frost protection thermostats.  Especially useful in remote location applications which demand long-term stability and maximum service life.

Matsuo thermostats are precision calibrated and then sealed within a PBT plastic housing giving excellent environmental resistance.  Calibrations from -10°C to +110°C are available with setting tolerances down to ±1.5K and differentials (hystereses) down to 3K.  AC loads up to 3A(250V) or 5A(125V) and DC loads up to 1.3A/24V or 0.8A/48V can be switched.

For high temperature applications, the M2HA ceramic thermostat offer calibrations upto 400°C. Matsuo’s M3Z is a change-over S.P.D.T. thermostat that is useful for triggering secondary circuits (e.g. visual alarms) when a set-point is reached.  The Matsuo MQT11H, MQT11K and M2F are integral thermostat/thermal fuse designs that offer temperature control and ultimate protection in a sealed plastic case.  They are therefore useful for some hazardous area applications, i.e. those requiring BASEEFA approval or ATEX certification.
