The signals of the navigation receiver's second mark and the RF available for the customer`s use are generated simultaneously on two high-frequency outputs of the receiver board. In the presence of stable reception of signals from satellites of the GLONASS and GPS radio navigation systems, the board ensures the operation of the RF in the frequency binding mode according to the signals of the second timestamp (the so-called “disciplined” rubidium frequency standard mode) with a relative error of the actual value of the RF frequency of no more than ± 5.0.10-12.

Measurement of mass concentration in liquid and volume fraction of hydrogen in gases, temperature Monitoring of concentrations (including small ones) of dissolved hydrogen at energy facilities, in technological processes in various industries: in a gas trap, in bearing crankcases, shielded current lines, linings and zero terminals, residual hydrogen in oxygen after electrolysis; oxygen content in hydrogen inside the generator housing, in a float hydraulic seal, tank purge and hydrogen separation tank of the generator oil cleaning unit. 24 months warranty for deliveries across the Russian Federation Automatic temperature and barocompensation Three measurement modes KRV (concentration of dissolved hydrogen), mcg/dm3 % of volume share Temperature, °C Long-lasting, highly stable sensor The service life of the hydrogen sensor is at least 10 years High contrast LCD indicator Low power consumption Up to 2000 hours of continuous operation from a set of AA type elements Easy calibration with a standard calibrator

High-precision measurements of hydrogen concentration in the range of 95-100% Monitoring of the operation of electrolyzers, control of hydrogen purity in the processes of hydrogen cooling of generators, in the technological processes of chemical, petrochemical, metallurgical and other industries 24 months warranty for deliveries across the Russian Federation A new patented measurement method The device does not require calibration Selectivity of measurement Direct method of measuring molecular hydrogen Insensitivity to humidity, carbon dioxide, oil vapor Measurement time 3-5 min Simple, intuitive interface Minimum maintenance Self-diagnosis Routine maintenance no more than 1 time per year Long-lasting, highly stable sensor The service life of the sensor is at least 10 years Color touch screen

The device is made in a 19-inch rack design with a 4U stand. The rubidium reference generator RRS-002 provides up to 15 independent signal outputs with a frequency of 10 MHz (5 MHz). The device is designed for long-term uninterrupted operation both in round-the-clock continuous and in session mode. The high reliability of the generator is ensured by reserving the main generator blocks and, in case of malfunction of the active signal source, automatically switching to a backup one.
