HACH PHC28103 Water Quality Laboratory Refillable pH Electrode**New pH Probe in box with accessories. Everything in pictures is included. See pictures for further details.IntelliCALPHC281 is a digital combination pH electrode with built-in temperature sensor. The PHC281 is a pH refillable probe made for difficult samples. This laboratory pH electrode is shockproof with its Zeonor plastic body protecting down to the glass bulb sensing element. The electrode is available with a 3 or 1 m cable. The PHC281 refillable pH electrode has a high electrolyte flow rate and a large open junction ideal for difficult samples, such as Low Ionic Strength (LIS), Ultrapure, dirty samples and samples with high solids content. The PHC281 is not suitable for use with organic solvents. A 59-mL bottle of 2.44 M KCl Electrode Filling Solution is included with the probe. PHC281 pH Ultra probe is designed for premium performance, even in difficult samples. The high electrolyte flow rate and large open junction design provide fast response and stabilization.SpecificationsAccuracy: 0.02 pHApplication: Low Ionic Strength & Dirty SamplesCable Length: 3 m (9.84 ft)Electrode Type: Refillable Reference ElementFilling Solution: 2.44 M KCl solution (#2965026)Junction: Open JunctionKit: NoLength: 175 mm (6.89 in.)Method Type - Field: Refillable Reference ElementParameter: pHProbe Type: StandardProduct Kit - Model: PHC281Accessories Included: NoneRange: 0 - 14 pHReference Type: Ag/AgClResolution: 0.001/0.01/0.1Sample depth: 15 mm (0.59 in.)Sensor material: ZeonorSensor Type: pH GlassSpecial Features: Double junction referenceTemperature Accuracy: 0.3 C (0.54 F)Temperature Range: 0 - 50 C (32 - 122 F)Temperature Resolution: 0.1 C (0.18 F)Test requirements - Parameter Needed: pHMinimum Sample Depth (mm): 15Thermistor: ATCWarranty: 12 monthsWeight: 0.15 kgWhat's included?IntelliCAL Laboratory PHC281 pH electrode with storage soaker bottle, 3 m cable, 59-mL bottle reference electrolyte filling solution (2.44 M KCl solution), Test certificate, and Basic User Manual.(Please be advised that any warranty/guarantee/return policy provided from the seller is between the buyer and the seller only.
