If any damage has occurred during shipment, immediately notify your Dealer or the nearest Hanna Customer Service Center. [. . . ] The housing has been completely sealed against vapors and humidity. It also floats so that it can be quickly retrieved if accidentally dropped in the tank. The HI 1219 rugged pH electrode supplied with the meter is constructed using the latest double junction technology and a HANNA exclusive replenishable fiber junction. The electrode can be simply replaced and the rubber sleeve protects the connector against humidity and spills. It will run for more than 2000 hours continuously with two AA type batteries. Measurements are highly accurate and the meter can be calibrated in one point. · Ideal for hydroponics and greenhouses · Waterproof housing floats for quick retrieval · Simple one point calibration · Renewable junction with pull out salt-bridge · Long battery life. 1. 8. Molded eye Liquid Crystal Display pH calibration dial ON/OFF button DIN connector Protective sheath HI 1219 pH electrode Electrode protective cap OPERATIONAL GUIDE pH ELECTRODE CONNECTION & MAINTENANCE In order to protect pH against vapors and humidity, the DIN connector is shielded behind a waterproof sheath. · Slide the protective sheath down. Connect the HI 1219 pH electrode to the DIN connector and then slide the protective sheath back up all the way up to the pH casing. To ensure maximum protection, make sure the connector is completely covered. pH pH CAL TAKING pH MEASUREMENTS · Turn the meter on by pushing the "ON/OFF" button. · Remove the protective cap from the pH electrode and immerse it's tip in the sample. · Allow the reading to stabilize and note the pH value on the LCD. 3 cm (1¼") CALIBRATION pH pH CAL 5. 8 ON/OFF For better accuracy, frequent calibration of the instrument is recommended. In addition, the instrument must be recalibrated whenever: a) The pH electrode is replaced. d) At least once a month. CE DECLARATION OF CONFORMITY DECLARATION OF CONFORMITY We Hanna Instruments Srl Via E. Fermi, 10 35030 Sarmeola di Rubano (PD) ITALY herewith certify that the pH meter CALIBRATION PROCEDURE · Open a pH 7. 01 sachet. · Remove the protective cap from the electrode, rinse the tip and immerse it in the pH 7. 0 buffer solution. pH pH CAL HI 981408 has been tested and found to be in compliance with the following regulations: 7. 0 ON/OFF pH 5. 8 ON/OFF IEC 801-2 IEC 801-3 IEC 801-4 EN 55022 EN 61010-1 Electrostatic Discharge RF Radiated Fast Transient Radiated, Class B Electrical Safety pH CAL 5. 8 ON/OFF Note: the electrode should be submerged at least 3 cm (1¼") in the solution. Date of Issue: 26-10-1999 · Stir gently and then wait until the reading stabilizes. · Adjust the "CAL" dial until the LCD shows pH 7. 0. pH 7. 01 BUFFER SOLUTION 20 mL sacket D. Volpato - Engineering Manager On behalf of Hanna Instruments S. r. l. BATTERY REPLACEMENT When the batteries are weak, the numbers become faint, the meter does not switch on or can not be calibrated. HI 70007 The pH calibration is now complete. · Do not be alarmed if white crystals appear around the electrode protective cap. [. . . ] Avoid touching this glass bulb at all times. During operation, ESD wrist straps should be worn to avoid possible damage to the electrode by electrostatic discharges. Any variation introduced by the user to the supplied equipment may degrade the instrument's EMC performance. [. . . ]
