Apera Instruments AI5537 Value Series Portable pH Meter Kit for Soil

Features:

• Equipped with Swiss LabSen® 553 PVC 3-in-1 pH/Temperature Spear Electrode, designed for direct soil pH measurement. Say goodbye to slurry making.
• Intelligent Functions: Self-Diagnosis of out-of-range value and electrode invalidation, auto. calibration, electrode slope display, Auto. power-off, easy parameter setting
• Rugged Structure Design: IP57 waterproof rating; Soft silicone case gives you a firm and comfortable grip
• Powered by AA batteries; the foldable stand also allows use as a benchtop meter
• Apera PH850-SL Portable pH Meter Kit: Designed for professional direct soil pH measurements. The equipped Swiss LabSen 553 3-in-1 pH/Temp. Electrode adopts Polymer electrolyte, Long-Life reference system, and a unique blue spear sensor tip, making precise direct soil pH measurement easier than ever.
• Built Tough: The IP57 water-resistant structure makes the meter ideal for use in harsh environment. The rubber sleeve protects the instrument from general impact and gives you a firm grip.
• Large LCD Display 
  • Stability icon. Take the reading when the smiley face stays on screen. 
  • Icons for finished calibrations  
  • Simultaneous temperature display
• LabSen 553: Powered by sensor technologies and key materials from Switzerland, Apera LabSen 553 PVC 3-in-1 pH/Temperature Spear Electrode, designed for direct soil pH measurement. No more slurry making.
• LabSen S-type spear glass membrane: Low resistance and high firmness, rendering fully stabilized readings in 15 to 30 seconds, and is yet 10 times stronger than traditional glass membranes, highly resistant to general impact, eliminating the chance of accidental breakage when inserting into the soil.
• Open&Ceramic double-junction with Polymer electrolyte: Ensures full contact with test samples while minimizing junction clogs. No need to refill electrolyte.
• Long-Life Reference System: Composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of reference system and extends the service life of the electrode.
• Electrode: LabSen 553 ATC Spear pH electrode Electrode
• Feature: PVC housing, spear sensor for direct soil test. 
• Application: soil (direct test, no slurry needed).
