TELNA Instruments, located near Toulouse in the South-West of France, was founded in 1977 and is specialized in designing and manufacturing high-performance electronic instruments for temperature measurement, calibration and control. This is why very important companies and state-approved organizations have been buying and using our products for years.

With 9 product lines, TELNA instruments proposes you 16 thermometers (for Pt100, Pt25, or TC) and two exceptional thermometers-regulators.

 

TN900 line

The TN900 line includes ultra-fine digital PID thermometers-regulators. TN900 (for use with Pt100) allows to stabilize the temperature at the desired set-point within 0.001°C (in liquids): the measurement section of this instrument is a highly precise thermometer (TN700) which stability supports this exceptional regulation performance. TN900TC is for use with S-type thermocouple probe and benefits from the measurements performances of the TN850 thermometer (with in particular an impressive CJC tracking performance). PID parameters and set-point can be set manually (with keys) or remotely (via RS232).

TN850 line

The TN850 line includes a high precision thermocouple (S or R) calibrator over the temperature range 0°C to 1500°C. The internal automatic (and linearized) Cold Junction Compensation function allows to get an outstanding tracking performance of 0.003°C/°C between 0 and 50 °C.

TN750 line

The TN750 line includes extremely high precision thermometers for use with ITS90 Pt100 sensors (optionally Pt25.5). TN750 & TN750S single-channel thermometers feature a very high stability better than 0.001°C+7ppm Rdg per year. TN750S offers a finer resolution of 0.0001°C as well as outstanding performances in terms of temperature coefficient (0.5ppm/°C max.) and short-term stability (0.00005°C). TN751 differential thermometer accepts two input channels (two Pt100 sensors) and delivers (with a resolution of 0.001°C) independent absolute measurements as well as differential measurements.

TN700 line

The TN700 line includes very high precision thermometers for use with ITS90 Pt100 sensors. TN700 & TN700MT single-channel thermometers feature a very high stability better than 0.005°C+18ppm Rdg per year and a temperature coefficient better than 1.5ppm/°C (max.). TN700MT is mounted in 2U-19" rack case and provides a linearized analog output (4/20mA for +20/+80°C. Also, tests at 5 and 50°C are possible with TN700MT thanks to integrated very high simulation resistances (55ppm max./year). JBUS protocol is available with TN700MT and optionally with TN700. The TN700 line also includes the TN701 differential thermometer that accepts two input channels (two Pt100 sensors) and delivers (with a resolution of 0.001°C) independent absolute measurements as well as differential measurements.

TN700R line

The TN700R line includes precision thermometers for use with ITS90 Pt100 sensors. Both TN700R & TN701R thermometers offer a resolution of 0.01°C over the range -180 to 650°C. The warranted long-term stability is better than 0.01°C+25ppm Rdg per year and temperature coefficient is less than 2ppm/°C (max.). TN701 differential thermometer accepts two input channels (two Pt100 sensors) and delivers independent absolute measurements as well as differential measurements.

TN600 line

The TN600 line includes data-logger thermometers (for use with Pt100 probes) with a resolution of 0.01°C. TN600P is battery power and ensures an autonomy of 400hrs. All products in this line (TN600P & TN600S) implement statistical functions (min., max., average, filtering, recording...).

TN500 line

The TN500 line proposes at very low cost a quality thermometer (TN500) with a resolution of 0.01°C (over the range -180 to 650°C) and a long-term stability (of 0.01°C+0.01% rdg per year) impressive for this price.

TN8 line

The TN8 line includes multi-channel thermometers (for 8, 12 or 16 input channels) that offer very high precision measurements to an accuracy of +/-0.002°C or better (when used with ITS-90 Pt100 sensor) with resolution at an impressive 0.001°C (over the entire range -180 to +650°C). Channel selection is performed either manually or automatically (scanning) or remotely. The TN8I, TN12I and TN16I thermometers also feature a permanent supply of the 8, 12 or 16 attached Pt100 probes.
