The comparator CHK7-1012 has a communication interface with an external personal computer USB 2.0 and application software for an external PC. At the request of the customer, the comparator can be supplied complete with a laptop or tablet computer with installed software.

Measurement of the activity of hydrogen ions (pH, pH25) of "ultrapure" waters (including water with a reduced electrical conductivity of 0.055 microns /cm) and alkaline waters containing ammonia or amines. Measurement of electrical conductivity (UEP, UEP25), temperature of aqueous media. Control of water-chemical regimes at energy facilities. A new patented measurement method that does not require calibration. The absence of elements that degrade in "ultrapure" water. Convenience and accuracy of measurement | Automatic thermal compensation. Freely programmable measurement ranges. Measurement of conductivity in the range up to 30 microns/cm. Communication with external devices | Galvanically isolated current outputs 0-5/4-20/0-20 Ma. RS 485 port. MODBUS RTU exchange protocol. Relay of "dry" contacts (6 pcs.) with programmable functions.

Intelligent data processing algorithms. 5.7" graphic touchscreen display, 65535 colors, resolution 640*480 pixels.

Mathematical processing of the measurement makes it possible to determine and display on the indicator board the relative systematic change in frequency, the average relative value of the frequency difference, the RMS relative frequency deviation, the RMS relative two-sample frequency deviation.

The Ch1-1012 frequency standard is designed for mobile applications with high requirements for dimensions, weight and power consumption as an embedded signal source of high stability in frequency measuring devices and complexes, telecommunication systems, navigation and communication systems. This device can serve as a promising substitute for quartz generators in the development of high-resolution equipment, where the accuracy characteristics of a quartz generator are no longer sufficient.

Two channels Freely programmable measurement ranges. The possibility of independent measurements at two points. Convenience and accuracy of measurement, minimum maintenance Automatic temperature and barocompensation. Automatic air oxygen calibration. Long-lasting sensor The service life of the sensor is at least 10 years. The possibility of placing the converter unit at a remote distance from the sampling point Up to 100 meters. Communication with external devices Galvanically isolated current outputs 0-5/4-20/0-20 Ma. RS 485 port, MODBUS RTU exchange protocol. Programmable setpoints with a "dry contact" type output. Durable IP65 aluminum housing The device is reliably protected from dust and moisture. Graphic indicator with backlight Convenient data presentation format and ease of settings

The module uses connectors of the SMA type. At the request of the customer, any combination of output signals is possible. When installing two amplifier modules in the above devices, the total number of output signals increases to twelve.
