Overview

Three reasons why you need the DR58EU

1. Sensitive and durable

The DR58EU detects faster and lasts longer. With a 1 g/year sensitivity, the DR58EU can clearly detect all the smallest leaks and the detector even responds to Tracer Gas (95% N2 + 5% H2). And you don’t have to worry about the DR58EU dying on the jobsite, with an 18-hour battery life the DR58EU will always last you until the end of the job. And with the option to either recalibrate every three seconds automatically, or choose the calibration interval by doing it manually, you can always be sure you use exactly what you need.

2. High-quality diode sensor

The diode sensor has the highest sensitivity to detect the smallest leaks and it’s also user-replaceable. No need to worry about getting a whole new tool when it’s just your diode sensor that needs replacing! And, you can do it all by yourself. Easy and fast diode replacement, that’s what we like.

3. Easy-to-view measurements

Because of the large LCD display that’s built in the Heated Diode Sensor, you can easily and quickly view the measurements of the DR58EU under any circumstances.

Frequently asked questions

Why is my leak detector alarming?

If no sensor is installed or the installed sensor is faulty when the unit is turned on, an alarm will sound and the unit will turn off.

What is the difference between automatic zero and manual zero?

Automatic zeroing on the instrument allows for convenient pinpointing of a refrigerant leak by setting a new 'zero-value' every 3-4 seconds. This is useful when a large concentration of refrigerant is being detected in a contained area. Manual zeroing puts the control of the zero function in your hands, you can simply press the zero button on the tool at any time to set a new zero value. This is good for clarifying the leak source once it has been identified.

How do I use low/medium/high?

Set the sensitivity level by pressing the Sensitivity button. Low (L), medium (M), or high (H) sensitivity will be indicated at the top of the LCD display. The higher the concentration of refrigerant in the ambient air, the lower the sensitivity setting should be to minimize false trips.

What is the difference between the DR58 and DR82?

The DR58 uses a heated diode sensor. The heated diode’s advantage is that it detects absolute concentration levels so it can be held on a leak and will continue to beep. It is also initially very sensitive. Its disadvantage is that the sensor becomes less sensitive over life, eventually needing replacement. The DR82 uses an infrared (IR) sensor. It detects a change in concentration, so the wand must keep moving. The advantage of the Fieldpiece IR sensor and its sensitivity is that it will last the lifetime of the instrument.

How do I replace the sensor?

First you need to order a new replacement sensor "RHD1". To replace the sensor, make sure the unit is turned off. Unscrew the wand on the DR58 and gently pull the sensor from the base. Now you can install the new sensor and put it back together.
