Hygrometer with built-in sensor P18D PCE Instruments

Product description:

• This hygrometer is an ideal instrument for monitoring and measuring indoor environmental conditions.
• It has a device that, through electromagnetic properties, receives information about the values to be measured.
• It is a compact model ideal for wall mounting, with an integrated sensor.
• It has a small screen on which the data is displayed.
• It has a Modbus interface that allows data to be collected and transferred to another device.
• The dimensions are 5.8 cm wide x 11.8 cm high x 3.5 cm deep.
• It weighs 125 g.
• It is IP65 protected, so it is protected against dust and water.
• Delivery includes 1 hygrometer, 1 USB cable, 1 memory card and 1 simple instruction manual.
