High technology in an excellent package

The design of the THERMO® TH3 is based on the excellent appearance. The simple and modern features of the meter brings many benefits in the installation and usage phases.

Easy to use

Six different menu for all you need can be reached easily using only one buton. The ability to read LCD messages is more safe with bright white colored backlight even in darkness area. Big digits, clear messages and symbols allow us to ensure a simple and easy reading of the display.

Eco friendly

THERMO® TH3 is powered by only one Li-SOCl2 batteries with more than 10 years service life. You will save battery changing service cost for 10 years. All electronic components have RoHS (The Restriction of Hazardous Substances Directive 2002/95/EC) compatibility.

Interfaces

Optical Port :Via the optical interface, data can be restored 15 years back in time, for communication and testing, MBUS protocol, 2400baud
MBUS :Selectable telegram, meets EN 13757-3, data reading and parametrization are via two wires with polarity reversal protection, fixed 2400 baud rate, exchangeable primary and fixed (8 digits serial number) secondary addresses
Radio :Real data, EN 13757 wMBUS T1 mode and OMS with 1 min transmit cycle
RS485 :Serial interface for communication with external devices, no need any external power supply, MBUS protocol, 2400 baud
Pulse Out :Class OD (Item 7.1.3 of EN 1434-2:2007) 1 kWh/ imp energy pulses
Pulse Input :Class ID (Item 7.1.6 of EN 1434-2:2007), data can be transferred remotely

Installation made simple

THERMO® TH3 has a capability easy mounting horizontally, vertically mounted on the walls whether on the ceiling, just above the ground or in narrow shafts. The flow sensor with IP68 high protection class and split calculator unit makes THERMO® TH3 flexible for every use.
