1. Introduction
The YSI Model 60 Handheld pH/Temperature System is a rugged, micro-processor based, digital
meter with an attached pH and temperature probe. The pH sensor can be easily replaced in the
field.
The Model 60 has a non-detachable cable available in lengths of 10, 25, 50 or 100 feet (3, 7.6,
15.2 or 30.5 meters). The probe body has been manufactured with stainless steel to add rugged
durability and sinking weight.
The YSI Model 60 has the following features:
• Capability to measure at depths of up to 100 feet (30.5 meters)
• Microprocessor control
• Field replaceable low maintenance pH sensor
• Push-button calibration
• Simultaneous display of pH and temperature
• Automatic temperature compensation
• Data storage for 50 sets of readings with on screen recall
• Waterproof case (IP65)
The Model 60’s micro-processor allows the system to be easily calibrated with the press of a few
keys. Additionally, the micro-processor performs a self-diagnostic routine each time the
instrument is turned on. The self-diagnostic routine provides useful information about the
function of the instrument and probe.
A transport chamber, built into the instrument case, provides a convenient place to store the
probe when transporting the system. The Model 60 case is waterproof (rated to IP65) allowing
operation in the rain without damage to the instrument.
The Model 60 is powered by six AA-size alkaline batteries. A new set of alkaline batteries will
provide approximately 100 hours of continuous operation. When batteries need to be replaced,
the LCD will display a “LO BAT” message.
The YSI Model 60 is designed for use in environmental, aquaculture, and industrial applications
where accurate pH and temperature measurements are desired.
