An affordable way to take consistent, accurate conductivity measurements in your laboratory! Dual display shows conductivity and temperature. Reads 0 to 199.9 mS across five ranges-autoranging feature gives the best resolution for your measurements. Calibrate at up to five conductivity points (one per range). Features adjustable temperature coefficient for better accuracy and selectable cell constant for very high or low range measurements. Memory stores up to 50 readings for future retrieval. Selectable manual or automatic temperature compensation. Ready indicator, HOLD, and water-resistant membrane keypad. Meter includes convenient pull-out reference guide, conductivity/temperature probe 35608-50 (K=1.0), built-in electrode stand, 110 and 220 VAC power adapters, and instructions. Three-year warranty on meters only. Dimensions: 9"W x 2 3/8"H x 7"D. Shpg wt: 3 lb (1.4 kg). Specifications: Conductivity (µS): Range: 0 to 19.99/199.9, 0 to 1999, 0 to 19.99/199.9 mS.
