Product Description
Product Overview:
The PM300 is a resistance (Pirani) vacuum transmitter with the functions of vacuum measurement, display, control, and transmission. It features a small size, convenient installation, and easy operation. The resistance gauge measurement adopts the constant temperature measurement method, which offers high precision and a fast response. It uses a fully digital calibration method, making it easy to operate. It is suitable for the measurement and control of medium and low vacuum.
