PONPE 523DO DO Meter / Temp เครื่องวัดออกซิเจนในน้ำ และอุณหภูมิ

DO electrode with easy to replace screw-on membrane cap

Dissolved oxygen to determine water quality in environmental testing, labs, industrial and municipal wastewater, aquariums, and fish hatcheries.
Designed for simple one-hand operation with Automatic Temperature Compensation and calibration to air.
The polarographic electrode has a built in temperature sensor and easy-to-replace membrane cap. 
The meter displays Oxygen level as a percent of Saturation from 0 to 250. 0 percent or Concentration from 0 to 20.00 ppm (mg/L).
It also features Adjustable Altitude Compensation (0 to 20,000 feet in 1,000 ft. increments), Adjustable Salinity Compensation from 0 to 50 ppt, and the large 4-digit display with analog bargraph for indicating trends.
Complete with a DO electrode, protective sensor cap, spare membrane cap, electrolyte, 1.0m neck strap, and four CR-2032 batteries.
