  Two different options of the HOT63 transmitter are 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 of sensors. The HOT63 is able to display the measured value in PPM, % Saturation, mmHg and p02 as well as displaying the process temperature in °C or °F. |
 The MOD53 has the flexibility to select either galvanic or polargraphic sensors, temperature compensator selection of Pt100, Pt1000, 1K ohm or 22K ohm thermistor and providing software selection of bias voltage and membrane coefficient, a single instrument may be used with virtually any dissolved oxygen sensor. A universal power supply allows a connection to any supply between 85 to 250v AC/DC. An option for low voltage operation between 18-36v AC/DC is also available. Up to 3 relay outputs offer on/off control with variable hysteresis and time delays if required. New features include a latch relay operation where the control relay can have a high and a low setting. Up to 2 industry standard, isolated outputs provide retransmission of the measurement as 0/4-20 mA signals and can be configured as any of the available measurement ranges or temperature. |
  The HD2109.1 and HD2109.2 are portable instruments with a large LCD display. They measure the concentration (in mg/l) of dissolved Oxygen in liquids, the saturation index (in %) and the temperature using SICRAM combined probes of polarographic type with two or three electrodes and integrated temperature sensor. Temperature only is measured by Pt100–SICRAM or direct 4 wire immersion, penetration or contact probes. Thanks to an internal pressure sensor, the instruments automatically compensate for barometric pressure. The instrument anticipates automatic compensation of the Oxygen probe membrane permeability and of the salinity of the liquid being examined. The dissolved Oxygen and temperature probes are fitted with an automatic detection module, with the factory calibration settings already being memorized inside. The HD2109.2 is a datalogger and memorizes up to 18,000 dissolved Oxygen concentration readings and other parameters.
