HI98131 เป็นเครื่องวัดแบบปากกา 3 IN1 เครื่องวัด EC และเครื่องวัด TDS ถูกออกแบบมาสำหรับงานปลูกพืชไร้ดิน (Hydroponics) ใช้งานง่ายสอบเทียบด้วยน้ำยามาตรฐานสอบเทียบ Quick Calibrate pH/EC เพียงขวดเดียว พร้อมใช้งานแถมน้ำยาสอบเทียบมาให้ครบชุด เหมาะสำหรับการเพาะเลี้ยงสัตว์น้ำ การปลูกพืชไฮโดรโปนิกส์ ปลูกพืชไร้ดิน ห้องปฏิบัติการและการทดสอบทางวิทยาศาสตร์ สระว่ายน้ำ สปา
The HI98131 measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with selectable EC to TDS conversion factor. The pH readings are displayed with a 0.01 resolution and with an accuracy of ±0.05 pH. EC and TDS readings are displayed with a 0.01 mS/cm and 10 ppm (mg/L) resolution and 2% full scale accuracy. The EC range of the HI98131 is from 0.01 to 6.00 mS/cm and TDS is from 0 to 3000 ppm using a 0.5 conversion factor or 0 to 3999 with a 0.7 EC to TDS conversion factor.
- 3 parameters, pH, EC/TDS, and temperature in one meter
- Quick Cal Mode to calibrate pH and EC/TDS with one solution
- TDS Conversion Factor selectable between 0.5 (500 ppm) and 0.7 (700 ppm)
One or two point pH calibration is automatic to a pre-programmed buffer set (4.01, 7.01 and 10.01) or single point pH and EC calibration with the Hanna Quick Cal calibration solution.
HI73127 Replaceable pH electrode
The HI99131 is supplied with the HI73127 replaceable pH electrode. This electrode features an extractable junction that can be pulled 1/8″ out to clear any clogging that results in drifting and erratic readings.
