Since the founding of the company in 1960, we have been concentrating our efforts on temperature control devices. Matsuo is the only one manufacturer in the world able to satisfy our customers' strong needs for a smaller differential, longer life, smaller size and lower cost.

In the area of bimetallic thermostats, in particular, we are the only supplier in the world focusing on the control type thermostats and the continuing development of products in this field.

The TPS enables the temperature control of precision measurement equipment and electronic equipment, which is the role of the electronic controller, via the bimetal. Furthermore, we have attained ultra high temperature control at a 400 degree level, which is the first time in the world. Our products demonstrate superior cost performance by achieving absolute performance equivalent to that of expensive sensors while maintaining a low cost and simple structure.

On the other hand, for applications where the TPS cannot fully satisfy the necessary requirements, we recommend the MET series electronic thermostat, which is simple to operate.

For customers who have been struggling between the two conflicting factors of "cost" and "performance", your problem will disappear once you've selected our thermostat products. If you are looking for the best product in the world in terms of procurement cost and absolute performance, "Matsuo" is the brand you should be looking at.

The bimetal type thermostat from Matsuo, which replaces the electronic type thermostat, is an outstanding thermostat which utilizes four factors, namely, a "small differential", "long life", "small size" and "low price", which nobody in the industry has been able to achieve altogether at one time.

Have you ever seen such a small-sized electronic thermostat with a thermistor?

Our advanced technology for mechanical thermostats is also utilized in the development of electronic thermostats where higher accuracy temperature control performance is required. Matsuo's miniaturization technology is contributing in the field of electronically-controlled thermostats, as well, where none of our competitors can even get close to us.

In the case of bimetal disk type thermostats, it is difficult to guarantee the heat resistance performance of the constituting material. As a result, there is no other bimetal thermostat product existing on the market, other than Matsuo's, which can control a high temperature range exceeding 230 degree.
