THERMOHYDROMETERS
Thermohydrometers are universal densitometers with integrated thermometers and are intended to measure the density of any liquid, regardless of the value of its surface tension. The reading should be performed at a temperature equal to the reference temperature (20°C) and within the range of the densitometric scale. Correct reading of concentration of a solution is achieved by the top reading. (look in „Useful information – Top reading vs. botom reading”)
The standard range of the thermometric scale is -10 °C to +30 °C (±5 °C).
The standard graduation of the thermometer is 1 °C.

Thermohydrometers for mineral oils
Thermohydrometers for mineral oils are intended to measure the density of mineral oils and their mixture, as well as of other petrol-based products and their mixtures. The reading should be performed at a temperature equal to the reference temperature (15°C or 20°C) and within the range of the densitometric scale. Correct reading of concentration of a solution is achieved by the top reading. (look in „Useful information – Top reading vs. botom reading”)
The standard range of the thermometric scale is -10 °C to +40 °C (±5 °C).
The standard graduation of the thermometer is 1 °C.

Thermohydrometers for ethylene glycol
Thermodensitometers for ethylene glycol are intended to measure specific gravity expressed in percentage by volume and to determine the degree of freezing of glycol. The reading should be performed at a temperature equal to the reference temperature (20°C) and within the range of the densitometric scale. Correct reading of concentration of a solution is achieved by the top reading. (look in „Useful information – Top reading vs. botom reading”)
