Introduction: PHD-99S transmitter is an intelligent industrial on-line instrumentation, flameproof structure design, advanced features and cost-effective, suitable for sewage treatment, wastewater monitoring, water testing, acid-base neutralization and chemical reactions and more Monitoring and Control of pH / ORP Values in Industrial Processes. Features: 1. Intelligent instrument, through the two key calibration and parameter settings, view the performance parameters of the electrode, the operation is simple and convenient; 2. Blue backlit LCD with pH (mV), temperature, output percentage at the same time; 3. 24VDC two-wire system, the output range of 4-20mA can be set arbitrarily; 4. Manual / automatic temperature compensation, PT100 / PT1000 temperature sensor can be set by the scene to switch; 5. Standard calibration and parameter adjustment, through the key operation; explosion-proof occasions can use the magnetic rod in the shell outside, more secure and reliable; Technical Parameters: Measuring range: pH 0 ~ 14pH ORP -1999 ~ +1999 mV Instrument stability: ± 0.05pH (2mV) / 24 hours Measurement error: ± 0.05pH (2mV) Instrument resolution: 0.01pH (1mV) Measurement shows: pH (or mV), temperature value Input impedance: more than 3 × 1012Ω Output signal: 4 ~ 20mA. DC; Output load resistance: 0 ~ 500Ω Working environment temperature: -10 ~ 55 ℃ Temperature compensation element: Pt100 or Pt1000 Temperature compensation range: -10 ~ 100 ℃ Temperature compensation error: <0.005PH / ℃. Power supply: 24V DC ± 10%; Electrical Interface: M20 * 1.5 Protection class: IP65 Explosion-proof grade: Flameproof ExdIICT6Gb
