Main features

ST-230 / ST-230L
Tilting head type for measuring surface temperature accurately

The tilting head allows tight contact with the measured object for accurate surface temperature measurement.

　

The dimpled grip fits into your hand (even with a glove) for stable measurement.

ST-30 / ST-30L
The small head of this sensor is suitable for measuring surface temperature of a small object or in a small space.

The sensing head of this sensor uses stainless steel for durability at high temperatures.

ST-32 / ST-32L
The stainless steel made sensing head is suitable for measuring high temperatures.

The stainless steel made sensing head is suitable for measuring high temperatures.

ST-29 / ST-29L、ST-29H / ST-29HL
Sensors for high temperature range with enhanced high temperature durability

The stainless steel made head with guide pins enables high durability against high temperatures.
　

ST-29 / ST-29L are used for measuring temperature up to 800°C
ST-29H / ST-29HL are used for measuring temperature up to 1100°C.
