The PCE-MA 202 is an oven-drying relative humidity meter for weighing and heating material samples to determine moisture content. The heating chamber warms up to 199 °C / 390 °F with the use of halogen lamps. Drying of the sample to be weighed takes place within the chamber of the relative humidity meter and the moisture content is subsequently calculated from the difference between the initial and final weight.

• Testing or weighing capacity: 200 g / 7.05 oz
• Readability: 10 mg / 0.01 g / 0.1%
• Adjustable drying temperature and time

PCE-MA 110 is a halogen relative humidity meter or analyzer that functions on the gravimetric or loss on drying (LOD) principle. The relative humidity meter uses the halogen method to dry the material sample. Moisture content is calculated based on the weight difference before and after the drying procedure. Calibration of the relative humidity meter can be performed at any time using the automatic calibration function and the included 100 g weight.

• Weighing range: 0.1 g … 110 g / 0.0035 … 3.88 oz
• Weighing resolution or readability: 0.01 g / 10 mg
• Moisture content measuring range: 0 … 100%
• Moisture content resolution or readability: 0.1%
• Adjustable drying time and temperature
• Memory stores up to 16 drying profiles
• RS-232 interface or port

The PCE-HT 71N Relative Humidity Meter detects air temperature and humidity and stores readings in its internal memory. The Relative Humidity Meter has a compact format and a wide memory capacity (up to 32,000 values / 16,000 values for each parameter) and it is mainly used as a Relative Humidity Meter in fields such as supermarket refrigeration units, refrigerated transport, warehouses, and other temperature controlled environments.

• Measurement range: 0 … 100% RH / -35 … 80°C / -31 … 176°F
• Accuracy: ± 3% RH (20 … 80%) and  ± 5% / ± 1°C (1.8°F)
• Resolution: 0.5% RH / 0.1°C (0.18°F)
• Memory: Max. 32,000 measurement data (16,000 for each parameter (humidity / temperature))
