Description
เครื่องมือวิทยาศาสตร์ อุปกรณ์วิทยาศาสตร์ 4 in 1 เครื่องวัดค่าการนำไฟฟ้า(Conductivity), เครื่องวัดตะกอน (TDS) เครื่องวัดความเค็ม (Salinity) and Temperature
EXTECH EC400 : ExStik® Conductivity/TDS/Salinity Meter ยี่ห้อ Extech, USA
4-in-1 multi-range sensor for measuring Conductivity, TDS, Salinity and Temperature
- Autoranging meter offers 3 ranges of measurements from tap water to wastewater and any aqueous solution
- Units of measure include µS/cm, mS/cm, ppm, ppt, mg/L, and g/L
- Adjustable Conductivity to TDS ratio factor from 0.4 to 1.0 – conveniently calculates the TDS value
- Large 3-1/2 digit (2000 count) Digital display with analog bargraph to indicate sample trends
- Data Hold, Auto Power Off and low battery indication
- Automatic Temperature Compensation of 2% per °C
- Simultaneous display of Conductivity, TDS, or Salinity plus Temperature
- Internal memory stores up to 25 labeled readings for easy recall
- Self calibration of electronics on power up
- Order Conductivity standards separately
- Complete with meter and Conductivity cell, protective cap, sample cup, four CR2032 batteries, and 48″(1.2m) neckstrap
