HI504 pH/ORP Controller with Sensor Check

™ Digital Transmitter Input Many industrial applications require distancesfrom the regulation system to the probe greater than the 15 meters provided byindustrial probes. For these situations, theuse of a transmitter is necessary.All HI 504 models are supplied with adigital transmitter input. Compared to atraditional analog transmitter, which has a maximum transmission length of 300meters, our new digital transmitter,HI 504910 permits the connection with the controller at distances up to 1.2 km. Thedata transmitted can be pH, mV and temperature.This digital transmitter is compatible withthe Sensor Check™ function and therefore guarantees excellent precision with continuousprobe inspection.

GSM Cellular Module Programmable auto-cleaning cycle
The optimization of an industrial processplant means the reduction of costly unsched- uled shutdown time. With this in mind,HANNA Instruments® has developed theHI504900 GSM cellular module* (optional). The HI 504900 is used for sending SMS alarmmessages* and also requests live updates onactual process conditions from authorized personnel.The GMS cellular module can memorize oneor two mobile phone numbers, where alarm messages can be sent whenever a malfunc-tion is revealed. The SMS message immedi-ately reports the nature of the alarm. Some causes include: Damaged pH probe, Damaged temperature probe or High setpoint exceeded. Fail safe alarm system Automatic temperature compensation Programmable hold system
pH/ORP Controller with Tele-control and Sensor Check HI 504 introduces an innovation in the concept of pH and ORP control, that enhances theentire line of process controllers engineered by HANNA instruments®. Over 25 years of experiencein the production of industrial controllers have enabled us to develop this series of highperformance instruments with our new tele-control technology. This technology supplies the means to control, from whatever distance and in real time, one or more installations, allowingthe user to optimize operations such as maintenance cycles. With two-way communicationsupplied by the RS485 output and Windows® compatible software, users can control the complete regulation process from the PC or through SMS via cellular phone.Measurement reliability is guaranteed by many self-diagnostic and troubleshooting functions,such as our innovative Sensor Check™ feature which is the result of advanced research and application know-how.The universal BNC connector allows the use of any type of industrial probe chosen for aspecific application, but at the same time renders probe replacement a simple and time saving operation.The HI 504 family offers a wide range of models, designed to fit your individual needs, and isable to satisfy whatever application of monitoring and regulation you require. * Compatible phones, plans & SIM cards must be purchased separately from an outside provider and is not in any way covered by HANNA Instruments® Industrial Products Catalog • www.hannainst.com 3
