Thermocouple technology has long been proven in laboratory and precision industrial instrumentation for sensing the deep vacuum range. Thermocouple sensors are factory calibrated and exhibit few of the electronic variances of thermistor sensors found in many other electronic gauges. Durable molded case with storage for sensor, cable and brass connector.

Thermocouple sensor features:

• No adjustments or warm-up. Stays calibrated after on/off switching and long evacuations
• Automatic battery compensation
• Automatic ambient temperature compensation
• Replacement sensor requires no calibration

LCD gauge features:

• Normal handling and jarring will not affect the LCD reading
• Case protects electronic circuitry and sensor
• Calibration standards traceable to NIST
• Precision circuitry controls sensor and translates sensor input into micron readings
• Made in the USA
