FIELD TEST
MEASUREMENT OF FIELD PARAMETERS COLOUR,ODOUR,TEM
PARATURE,EC,pH, DO ARE FIELD PARAMETERS AND ARE
TO BE ANALYSED AS SOON AS SAMPLE IS
COLLECTED MEASUREMENTS OF THESE PARAMETERS CAN
BE MADE BY USING FIELD KITS.THIS IS BEST
OPTION ANOTHER OPTION- NEARBY LEVEL-1
LAB D.O.SAMPLE MUST BE FIXED IMMIDIETLY AFTER
COLLECTION OF SAMPLE TEMPARATURE MUST BE
MEASURED AT THE SITE ONLY
