• Temperature range : -175°C (-283°F) to 50°C (122°F)
• Temperature control and resolution of 0.01°C
• One calibration that covers the whole temperature range is provided based on the NIST 1450b Standard
• Warranty - one full year parts and labor

Testing will require connection to a LN2 (Liquid Nitrogen) dewar. In order to reduce the use of LN2 the instrument will control the flow rate by a controlled solenoid valve on the dewar. A small portion of the exhaust gas is routed inside the test chamber in order to provide a dry atmosphere. The Instrument is capable of completing nine entered setpoints covering the entire temperature range within a day.

The guage pressure of the LN2 tank is 22 psig (151 kPa, 1.517 bars). Itwill use ~120 liters for a typical full range test of ~10 hours duration. Tests should begin at the lowest temperature and end on the highest. This is critical to removing the problems instroduced by condensation. The Lowest mean temperature is -165°C.
