A new, paperless, high-accuracy temperature/humidity logger with wireless and Ethernet capability and software triggered alarms is ideal for ISO/FDA audit data capture

For most models the stability has been improved from + 0.02°C to + 0.01°C. The units also feature a temperature stability countdown timer which starts five minutes before the stability indicator comes on. This helps the user to know when to take readings from the sensor-under-test.

The sensor's easy-to-read three-inch dial provides local temperature indication in 0-250°F and 0-500°F dial ranges, is hermetically sealed per ASME B40.3, and has field-adjustable calibration. The dial gauge has NIST traceable calibration of up to 1% of reading.

The BIMETAL requires no power supply at the point of measurement. It includes a rugged thermowell probe assembly that contains a Moore Industries’ RTD or thermocouple sensor, and a large analog display. Both the sensor and display are NIST traceable, and can be quickly calibrated in the field. No source of power is needed to drive the local analog readout; the thermocouple or RTD can be read via a standard transmitter, signal conditioner or analog input device.

The Pacific Sensor technologies PST-AR-892 High temperature infrared thermometer is tri-pod mountable and can be used to data log temperature critical events and communicate back to a PC via its integrated RS232 interface.

The detector, called a 'hot electron bolometer', is comprised of a small piece of superconducting niobiumnitride. A miniscule gold antenna catches the terahertz-radiation and sends it via the contacts to the small piece of niobiumnitride, which functions as an extremely sensitive thermometer...

Ideally suited to calibration applications in the pharmaceutical,
food, food ingredients, hospital and marine industries, the ATC-125
can be used to perform fully automatic calibration routines without
the need for a PC. However the unit is also fully compatible with PC
operation and is supplied complete with JOFRACAL calibration software

Compact, digital IR thermometer suited for applications with difficult ambient conditions

The VL can measure temperatures from -40°C to 700°C with a response time of just 180 ms. It has a narrow 10:1 field of view, and adjustable emissivity so can be configured to measure most materials. Each unit offers a choice of either 0/4 to 20 mA, 0 to 5 V or type J or K thermocouple outputs allowing them to be used with virtually all process control instrumentation.

Test samples with water from the Antarctic and water from New Zealand proved they were onto something. Further testing concluded that the source of water used in a triple point of water cell indeed had a much larger influence than anyone had realised.
