Thermocouple Instruments by GEC
Our standard 4 channel type T thermocouple instrument, Model S4TC, and our standard 16 channel type T thermocouple instrument, Model S16TC are normally in stock for immediate delivery. We also build custom instruments with type B, E, J, K, N, R, S or T thermocouple inputs and with up to 95 channels in the same enclosure.
And we can provide differential thermocouple inputs for very accurate measurements of small temperature differences. These units include a 6' serial cable, versatile Windows software, and a 2 year warranty. They may be connected to a USB port via a USB to RS232 adapter.
Specifications for our standard type T thermocouple instruments

Type T female miniature thermocouple input connectors.

Temperature measurement range: -200 to +400 °C
(-328 to 752 °F)

Operating Temperature: -10 to 50 °C
(avoid condensation)

Resolution of temperature measurement: 0.01 °C (0.018 °F).

Accuracy of temperature measurement: If the instrument is operated in an ambient of 15 to 35 °C, instrument accuracies better than ± 0.1°C (0.18 °F) can be attained over the measurement range of -10 to 100°C. Very high accuracies can be attained at higher and lower measurement temperatures as well. This specification includes all instrument errors including reference junction error.

Total system measurement accuracies (including thermocouple wire error) of 0.05 °C (0.09 °F) or better can be attained through software calibration of thermocouples by comparison with a known temperature standard. Click here to see some data.

Uniformity between thermocouples of 0.02 °C
(0.036 °F) enable accurate measurements of small temperature differences.

Built in auto zero eliminates system offset errors. Both 50 and 60 Hz. noise rejection are available.

Scan rate: 2 to 10 channels/second, depending on desired resolution.

Size: 3" high x 9" wide x 5.5" deep.
(7.62 cm. high x 22.9 cm wide x 14.0 cm deep)

Weight: 3.30 pounds (1.50 kg)

Shipping Weight: 5 pounds (2.27 kg)

Sturdy die cast aluminum case with light grey powder coating.

Communications protocol: RS-232, 9 pin female serial connector.

Options: Additional thermocouple channels, precision high accuracy (0.002 to 0.004 °C) high resolution (0.0002 °C) thermistor probes, 4 to 20 ma inputs, relative humidity inputs, custom thermocouple calibrations.
