HM Digital Portable Ph Ec TDS Temp Monitor HM-200

  
The hm-200 is a versatile portable ph/ec/tds/temp monitor ideal for all water quality testing, hydroponics, water purification applications, wastewater regulation, aquaculture, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more. Measures potential hydrogen (ph), electrical conductivity (ec), total dissolved solids (tds), salinity and temperature. Five scales: ph, s, ms, ppm 0.5 (nacl) scale & 0.7 (442) scale. Automatic temperature compensation (atc) using three temperature coefficients. Digital calibration (push button) to any point within the meter's range.

Auto-off function, data-hold function and low-battery indicator. Large and easy-to-read lcd screen. Displays 3 parameters (ph/ec or tds/temp) simultaneously. Replaceable sensors (model sp-c2 for conductivity, sp-p5 for ph). Includes protective rubber boot, 2 (aa) alkaline batteries, ph 4 & 7 calibration solutions, ph storage solution.
