Replace electrodes in seconds! Integral threaded cap assembly permits quick servicing for calibration or replacements. Electrode holders have threads on each end. Install holders into a pipe tee for in-line use or on the end of a submersion pipe. Holders are available in CPVC or chemical resistant KYNAR ® . Choose from a variety of sealed combination electrodes with or without automatic temperature compensation. Annular junction prevents clogging and allows fast, stable response. Electrodes include 10-ft, low-noise cable BNC connector--mount up to 1000 feet away using a preamplifier kit. Order holders, electodes and preamplifier kit separately. These electrodes are ideal for applications involving high-sodium concentrations. Double-junction reference protects against contamination from heavy metals, organics, and sulfides. Use for measurements from 0 to 14 pH. Electrodes withstand temperatures from 23 to 230ºF (-5 to 110ºC). Note: 100Ω RTD ATC elements conform to DIN curve 43760. ATC connect...

TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-EZ can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-EZ is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-EZ is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, and more.PH penprovides more reliable accuracy and durability for testing the acidity or alkalinity of liquids. It is very easy to use - just immerse the electrode and the readings are automatically displayed. With a resolution of 0.01pH and a 0.05pH range of error, yo...
