Scanning thermocouple monitor has 16
channels
The SR 630, now available in the UK from TTi (Thurlby Thandar Instruments), is a 16-channel thermocouple monitor designed to read, scan, print and log temperatures or voltages.
The SR 630, now available in the UK from TTi (Thurlby Thandar Instruments), is a 16-channel thermocouple monitor designed to read, scan, print and log temperatures or voltages For temperature measurements, one of seven standard thermocouples (B, E, J, K, R, S or T type) may be used to read temperatures between -200 and +1700C

Electronic loads offer high current capability
The Dynaload RBL Series of single-channel electronic loads offer an exceptionally high current rating of 1000A, and are ideal for the testing of large batteries and other DC power equipment.
Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
For many applications, type K thermocouples (Chromel/Alumel) offer a wide temperature range (-200 to +1250C) with a low standard error and good corrosion resistance.
Welded K-type thermocouples with either Teflon or high-temperature glass insulators are available from TTi as an optional extra.
Temperature readings from the SR 630 can be viewed on the front-panel display or downloaded via standard RS-232 and GPIB interfaces.
Convenient hard-copy output in either tabular or strip-chart format is available via the standard Centronics printer port.
Temperature measurements can be made up to 12 times per second, with values reported in degrees Fahrenheit, Celsius or Kelvin.
Programmable, audible alarm limits can be set for each channel.
A back-panel relay output is available to provide shutdown capability when the limit conditions are exceeded.
The SR 630 can also be configured as a 16-channel DC voltmeter with full-scale ranges from 30mV (luV resolution) to 100V.
As a voltmeter, the unit has 0.05% accuracy and luV input offset drift.
For increased flexibility, each channel can be set independently to monitor either temperature or voltage.
Four rear-panel outputs are also available to provide a voltage proportional to the temperature of the first four input channels.
The voltage outputs can be used to drive recorders or to control external instrumentation.
An internal battery-backed clock/calendar is used to time-stamp temperature readings.
The SR 630 can be set to scan, time-stamp and record up to 16 channels at intervals from l0 to 9999s.
Data is either sent immediately to the printer, or may be stored in the internal 2000-point buffer memory for output at a later time via RS-232 or GPIB.
The SR 630 costs ?1415.00 (plus VAT).
