supply of laboratory equipments for water testing laboratory sendhwa , microprocessor based conductivity-tds meter t-308 , ph system is an intelligent high resolution andprecise instrument. it measures ph of a solution, using aph electrode. the unit can also measure millivolt ( mv ) generated by the sensing electrode it is named as mv absolute a 7 ph solution. facility to measuretemperature using a pt 100 sensor is also provided. , nephelo - turbidity meter 132 & 135 is an accurateand elegent instrument designed for conductingnephelometric and turbidity measurements ofsuspended particles and colloids in solution. theprinciple of operation of this instrument is based on thewell-known tyndall effect. a beam of light passingthrough a turbid liquid being tested. scatters the lightwhich, in turn, is collected at right angles by aphotodiode and indicated in a display. the amount ofscattered light is proportional to the turbidity of thesolution under test. the application of turbiditymeasurements are vast in municipal, public health, sewage works and in industrial establishment fordetermining quality of water / waste water. , spectropohot meter is a micro controller based double beam scnning instrument uv-vis double beam wavelenoth range 190 to 1100nm, resolution 0.1nm. accuracy 0.5nm repenuablliy 0.2nm. bandwidh 1nm. five posltion automatic postioning for 50 / 100 mm sample cuvelle and one fixed position for refeerence cuvette & graphlo lcd with demo technical traning. acceptable make- systronic, hach, orion , mettler
