Table 1. Modbus measurement data registers (read-only)
Register number Address Description Data format Unit
1 0000hex Vaporized hydrogen peroxide concentration by volume 32-bit float ppm
3 0002hex H2O+H2O2 relative saturation 32-bit float %RS
5 0004hex

Temperature used for calculation. By default, shows the temperature from the temperature probe (register 0016hex).

If temperature compensation is turned ON (register 0505hex), this register shows the volatile value for given temperature reading (register 0302hex). See Table 1.

 32-bit float °C
7 0006hex Relative humidity 32-bit float %RH
9 0008hex Absolute hydrogen peroxide 32-bit float mg/m3
11 000Ahex H2O+H2O2 dew point temperature 32-bit float °C
15 000Ehex Water concentration by volume 32-bit float ppm
17 0010hex Water vapor pressure 32-bit float hPa
19 0012hex Absolute humidity (water) 32-bit float g/m3
21 0014hex Water vapor saturation pressure 32-bit float hPa
23 0016hex Temperature from the temperature probe 32-bit float °C
25 0018hex H2O2 vapor pressure 32-bit float hPa
27 001Ahex Water vapor saturation pressure (H2O+H2O2) 32-bit float hPa
257 0100hex Vaporized hydrogen peroxide concentration by volume 16-bit signed integer ppm
258 0101hex H2O+H2O2 relative saturation 16-bit signed integer %RS * 100
259 0102hex

Temperature used for calculation. By default, shows the temperature from the temperature probe (register 010Bhex).

If temperature compensation is turned ON (register 0505hex), this register shows the volatile value for given temperature reading (register 0302hex). See Table 1.
