We design, develop and commercialise high-end instrumentation products based on our proprietary technology.

The TELNA website presents a sample of our catalogue of measurement and regulation equipment and instruments, including:
- hyper-precision digital thermometers, including multi-channel (8 or 16) thermometers
- ultra-fine microprocessor-based temperature controllers

Features include:
- Super accuracy with a resolution from 0.0001?C (TN750S) to 0.01?C (TN601N-600S-600-600N-8N)
- Exceptional linearity (0.001?C see TN751, TN750S and TN750) over the entire temperature range
- Excellent long-term stability (0.001?C per year see TN750S and TN750)
- Temperature control and stabilisation (see TN900) of up to 0.001?C
- Isolated RS232 (ASCII) output
- Operator friendly features multi-function, easy to read, and large LCD graphics display
Sequential measurements at user programmable intervals (see TN16-8-8N multichannel thermometers)
- Automatic storage of consecutive temperature measurements (TN600P-600N) with logging at user programmable interval rangings
- Manual channel selection or via the RS232 communication (see TN600P and TN600N)
