Paperless recorders, transmitters and displays
Ten models across four families, made here rather than traded. The measuring ones sit in a panel, on a duct or on a wall. The recording ones exist because somebody has to prove what the temperature was, months later.
The range
Ten models, four families
Recorders that keep the record, transmitters that put a measurement on a 4–20 mA loop, displays that put it on a wall, and modules that put twelve channels on RS-485.

Specifications above are the published figures for each model. Range, output and supply are fixed per variant, so the exact item you need is a model plus those three choices — send the application and we come back with the code. Drawings and the full parameter sheet for any model are available on request.

Configuration
What changes between orders
An instrument is a model plus the choices below, not a catalog number to look up. These are the axes we set per order; anything not on the list is a conversation, not a refusal.
