Internal thermistor for optimized measurements
Overview
Kipp & Zonen's CMP22 has all the features of the CMP21 but uses very high quality quartz domes for a wider spectral range, improved directional response, and reduced thermal offsets. Because of the high optical quality of these domes the directional error is reduced below 5W/m2. Kipp & Zonen is confident that CMP22 is the best pyranometer currently available.
The "-L" on a product model indicates that the cable length is specified at the time of order.

Detailed Description
Kipp & Zonen's CMP22 provides a flat spectral response for the full solar spectrum range allowing use under plant canopies or lamps, cloudy conditions, or for reflected radiation measurements.
A waterproof socket is fitted for the signature yellow signal cable, which is available in a range of lengths pre-wired to the waterproof plug.
The integral bubble level is raised to the top of the housing and can be viewed without removing the redesigned snap-on sun shield, which also covers the connector. The screw-in drying cartridge is easy to remove and the replacement desiccant is supplied in convenient refill packets. The Pyranometer does not require any power, it supplies a low voltage of 0-20 mV in relation to the amount of incoming radiation. The CMP22 can be fitted with the CVF4 ventilation unit to further improve its performance.

Compatibility
Mounting
Kipp & Zonen's CMP22 has a bubble level and two leveling feet, which allow it to be leveled without using a leveling base. The 015 Mounting Arm can be used to mount the sensor to a mast or the CM225 Solar Sensor Mounting Stand can be used to attach the sensor to a mast, crossarm, or pole (1.0-in. to 2.1-in. outer diameter). The CM225 consists of rectangular plate, mounting bracket, U-bolts, lock washers, and nuts.
Alternatively, the CM245 Adjustable Angle Mounting Stand may be used. It includes slots that can be adjusted to any angle from horizontal to vertical. The L27084 can also be used to mount a pyranometer housed inside of the CVF4 heater/ventilator.
