Infrared pyrometer measures temperatures down to 350 degrees C

The new PyroMini 0.9 infrared pyrometer makes it possible to measure the temperature of reflective metals and semiconductors, as low as 350°C, at low cost and without contact.  The pyrometer can view into a vacuum chamber through a quartz or glass window, and measure the temperature of the surface of the silicon wafer.

Temperature ranges from 350°C to 2000°C are available, and the low-temperature 350°C to 800°C model opens up new opportunities for temperature monitoring and control in silicon wafer processing.

Stable and repeatable measurements can be taken continuously for long periods, with a fast response time of just 240 milliseconds. With the optional MicroSD Card installed, over a year of data can be logged, even at the fastest sample rate of one reading per second.

The highest possible accuracy is provided by the PyroMini 0.9’s short-wavelength detector, which ensures that any error in emissivity setting or change in emissivity has the minimum effect on the measurement.

The 18 x 45mm miniature sensing head is sealed to IP65. Cable length of up to 30 m is available.

An electronics module with optional touch screen comes with a large, bright temperature display, visual alarm indication, scrolling temperature graph, and full sensor configuration. Basic models without a screen are also available.

There is achoice of 4-20 mA or RS485 Modbus output, and two alarm relays on touch screen models that could be connected to alarm equipment directly, without a separate trip amplifier
