HOT63 Dissolved Oxygen Transmitters www.lth.co.uk The HOT63 Dissolved Oxygen transmitters combine modern technology with over 35 years of experience in building high quality sensors for liquid analysis to provide a range of competitively priced transmitters to cover a wide range of process applications. • Custom IP66 enclosure. • Available as Wall or rail mounted versions with detachable cables • Large back lit multifunction display • Simple intuitive programming. • On Line multilingual Help with text error messages • Dual isolated 4-20mA & relay outputs • Relays can be configured for On/off, Time & Pulse Proportional • Digital inputs for auto-cal, clean and off line operation • Measured process & temperature can be displayed together as can the corresponding 4-20mA output • Cable termination for supply & outputs via detachable connectors, no need to open enclosure • Low voltage operation 15-30V AC/DC • Measurement in % saturation, PPM, mmHg & p02 • Suitable for use with Galvanic or Polargraphic sensors • Active or manual pressure compensation

Two different options of the HOT63 transmitter will be available with the Base model offering a single industry standard 4-20mA output. The Advanced HOT63 will offer two 4-20mA outputs enabling the process temperature to also be measured and transmitted as well as the Dissolved Oxygen value. The Advanced HOT63 model will also have 2 relay outputs for process control and also has 3 digital inputs for remote range changing via a plc and Automatic pressure compensation from an external pressure transmitter. Both models are available as wall / rail mounting versions with a detachable cable & a choice...
