Single-channel thermal vacuum gauge with a large red LED display for continuous pressure measurement of dry air and nitrogen. This 2-relay / 1-analog-output / RS-485 / 4 MB archive configuration supports PMT-2, PMT-4M, SK-TP4 and SK-TS6 sensors. Sensor, cable, verification and exact options must be confirmed for the order.
Description
Meradat-VIT12T6 Thermal Vacuum Gauge
The Meradat-VIT12T6 is a single-channel thermal vacuum-gauge controller with a red LED display. It is intended for continuous measurement of dry-air and nitrogen pressure in laboratory and industrial vacuum systems. The selected sensor determines the usable pressure range and accuracy.

Measurement and Control
The two relay outputs can provide alarms or control external circuits. The analog output transmits the measured value to a control system, while RS-485 connects the instrument to a Modbus network. The ring archive stores recent measurement history.
Metrology Information
The source record identifies Russian State Register entry No. 41616-09, verification procedure MI 140-89 and a one-year verification interval. This status is jurisdiction-specific. Confirm the exact instrument modification, sensor, valid verification and acceptance in the destination country before use in a regulated measurement process.
The technical infographic, video and slide deck from the source page are intentionally omitted from this English page. Confirm sensor, connection cable, output options, archive size, relay rating, documentation and verification before ordering.
