Portable compact battery operated system for measuring Stomata conductance OR Resistance of leaves. The sensor head contains two fast response micro thermister to measure cup and leaf temperatures, allowing accurate temperature compensation to be applied.
AP4 has a in-built data storage facility for 1500 data sets and each data set comprising the readings, reading label, time, light level (PAR), temperature and relative humidity have facility to write 30 characters of note from key pad to identify the observation or any particular species. A help button in the instrument itself provides all the operational help to the user in field itself. AP4 is supplied with a modulated polypropylene
calibration plate to calibrate the instrument in the field itself with in few seconds.
