To analyze small concentrations of carbon monoxide (CO) and carbon dioxide (CO2), instead of the usual catarometer for these gases, a more sensitive PID is used, while carbon oxides are converted into methane (CH4) using reaction chromatography. The device implementing the conversion reaction is called a methanator, i.e. a device with a special catalyst that converts CO, CO2 into methane in a hydrogen current, while the latter is either a carrier gas itself, or is blown together with the carrier gas into the methanator through a tee. The methanator provides a highly efficient conversion reaction, while the detection limit of carbon oxides reaches 0.1 ppm. technical specifications Metanation temperature — 330 °C The coefficient of metanation is not less than 95 % The effective volume of the methanator is 1 ml.

The LOIP LT-112a modification device consists of an immersion thermostat-circulator LOIP LT-100 and a working bath with a flat removable lid. Design features: The LOIP ATC intelligent control system adapts the parameters of the PID controller to the type of working fluid and eliminates the influence of instability of the mains voltage and air temperature on the operation of the system. A productive discharge pump ensures efficient mixing of the coolant inside the bath and high accuracy of maintaining the temperature of an external object with a closed circuit. A bright LED digital display displaying the current and set temperature with a discreteness of 0.1 °C. Multifunctional control knob. Simple correction of the internal temperature sensor readings with the possibility of calibration by two points. A cooling coil connected to the water supply to reach temperatures below room temperature (installed on request, not included as standard). Self-diagnosis system with indication of the causes of malfunctions on the display. A safety device with a sound and light notification that provides automatic shutdown of heating in the event of a break in the temperature sensor circuit, as well as when the coolant level drops below the permissible level. Stainless steel working baths, made by stamping, are characterized by a long service life and ease of cleaning. The external body of the bath is made of powder-coated steel and is reliably insulated from the tank of the bath, which allows the operator to work safely with the equipment even at high temperature of the working fluid. Technical specifications: Temperature range: without external cooling, °C Current +10 ... +100 with tap water cooling °C Tvods+5 ...+100 Accuracy of temperature maintenance, °C ± 0.1 The error of setting the set temperature, no more than ° C ± 0.2 Heater power, W 1900 Pump: max. flow rate, l/min 7.5 pressure, 0.17 bar Bath volume, l 12 The working fluid is water, water-glycerin mixture.
