Instruction Manual HI 98129 • HI 98130 pH/EC/TDS/Temperature with Only One Tester Dear Customer, Thank you for choosing a Hanna product. This manual will provide you with the necessary information for a correct operation. Please read it carefully before using the meter. If you need additional technical information, do not hesitate to e-mail us at tech@hannainst.com. FUNCTIONAL DESCRIPTION These instruments are in compliance with the directives. PRELIMINARY EXAMINATION Remove the instrument from the packing material and examine it carefully. If any damage has occurred during shipment, immediately notify your Dealer or the nearest Hanna Customer Service Center. Each meter is supplied with: • HI 73127 pH electrode • HI 73128 electrode removal tool • batteries (4 x 1.5V) and instructions automatic, with β=0.0 to 2.4%/ºC (EC/TDS) Note: Conserve all packing material until the instrument has been observed to function correctly. Any defective item must be returned in its original packing. automatic, 1 or 2 point with 2 sets of memorized buffers (pH 4.01/7.01/ 10.01 or 4.01/6.86/9.18) for pH; automatic, at 1 point for EC/TDS GENERAL DESCRIPTION HI 98129 and HI 98130 are warranted for one year against defects in workmanship and materials when used for their intended purpose and maintained according to instructions. The electrode is warranted for a period of six months. This warranty is limited to repair or replacement free of charge. Damages due to accident, misuse, tampering or lack of prescribed maintenance are not covered. If service is required, contact the dealer from whom you purchased the instrument. If under warranty, report the model number, date of purchase, serial number and the nature of the failure. If the repair is not covered by the warranty, you will be notified of the charges incurred. If the instrument is to be returned to Hanna Instruments, first obtain a Returned Goods Authorization Number from the Customer Service department and then send it with shipment costs prepaid. When shipping any instrument, make sure it is properly packaged for complete protection. HI 98129 and HI 98130 are waterproof pH/EC/ TDS/temperature meters. The housing has been completely sealed against humidity and designed to float. All pH and EC/TDS readings are automatically temperature compensated (ATC), and temperature values can be displayed in °C or °F units. For EC/TDS readings, the EC/TDS conversion factor (CONV) is selectable by the user, as well as the temperature compensation coefficient β (BETA). The meters can be calibrated at one or two points for pH (with auto-buffer recognition and against five memorized buffer values), and at one point for EC. Measurements are highly accurate with a unique stability indicator right on the LCD. These meters are also provided with battery level indication at start-up, and with a low battery symbol which warns the user when the batteries need to be replaced. In addition the Battery Error Prevention System (BEPS) avoids erroneous reading caused by low voltage level by turning the meter off. The HI 73127 pH electrode, supplied with the meter, is interchangeable and can be easily replaced by the user. The stainless steel encapsulated temperature sensor facilitates faster and more accurate temperature measurement and compensation. All rights are reserved.

Recommendations for Users Before using this product, make sure that it is entirely suitable for the environment in which it is used. Operation of this instrument in residential areas could cause unacceptable interferences to radio and TV equipment. The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all times. Any variation introduced by the user to the supplied equipment may degrade the instrument’s EMC performance. To avoid electrical shock, do not use this instrument when voltages at the measurement surface exceed 24 Vac or 60 Vdc. To avoid damages or burns, do not perform any measurement

All the used segments on the LCD will be visible for a few seconds, followed by a percent indication of the remaining battery life (Eg. % 100 BATT). To change the temperature unit To change the temperature unit (from °C to °F), from measurement mode, press and hold the /MODE button until TEMP and the current temperature unit are displayed on the lower LCD (E.g. TEMP °C). Use the SET/HOLD button to change the temperature unit, and then press the /MODE button twice to return to...
