Electronic Refrigerant Gauges to Measure, Analyse and Document from testo

Refrigerant gauges measures temperatures and pressures in refrigeration and heat pumps

Category: Tag:
Business Name: Testo Pty Ltd


specialise in digital gauges for
refrigeration and temperature designed and priced to make analogue obsolete,
the Testo digital refrigeration manifold range includes the testo 549, testo
550, testo 557 and testo 570 models. An optional Bluetooth capability will also
allow users to connect to testo’s Refrigeration App, which is exclusively available
to testo customers.( Not applicable to Testo 570)

Testo APP & Bluetooth

The App integration via Bluetooth for testo 550 and testo 557 expands the
user’s ability to work faster and more efficiently. The App enables the user to
read measurement data directly on a smartphone or tablet, allowing them to
finalise and send measurement reports directly from the site. The list of
stored refrigerants can also be easily updated via the App.

testo’s digital manifolds make many of the typical refrigeration
contracting tools obsolete. The user can also select the most important
refrigerants for even faster access.

Better performance

Though analogue manifolds are still widely used in the
refrigeration industry, digital manifolds are the future of refrigeration
engineering. The new testo manifolds deliver enhanced performance with the
pressure ranges of the 549, 550 and 557 variants increased to 60 bar; battery
life extended to 250 hours; and choice of 60 common refrigerants stored in the
instrument. The robust design features a new metal frame around the display.

One instrument to cover every job

testo’s digital refrigeration manifolds are designed to
meet all the day-to-day challenges in refrigeration contracting, enabling the
user to measure various operating parameters with a single instrument. The
digital manifold helps the contractor get a comprehensive overview of the
condition of a refrigeration system or heat pump in real time.

testo’s new digital manifolds combine the price advantage
associated with analogue measurement with the undeniable precision of digital

testo 549: The best value manifold

Offering the best price-performance value among all the
models, the testo 549 digital manifold precisely measures high side/ low side
pressure and instantly displays the corresponding saturation/ evaporation
temperatures for 60 refrigerants. Optional temperature probes enable automatic
superheat and sub-cooling calculations to be displayed.

testo 550: Bluetooth capabilities and new Refrigeration App

Offering instant display of superheat and sub-cooling for
up to 60 refrigerants, testo 550 also measures high side/ low side pressures
and temperatures. The Bluetooth connection opens up new possibilities for
efficient analysis and documentation.

testo 557: Precision measurement

Offering all the strong points of testo 550, the testo
557 digital manifold will feature a 4-way valve block for fast, safe and
efficient work in commissioning, service and maintenance. A new highly precise
external vacuum probe delivers even more reliable performance

Testo 570 for the professional

The testo 570 refrigerant gauges measure and analyse pressures, temperatures,
vacuum or current whilst remaining easy to operate.

  • Simple design and
    function allows technicians to carry out time saving and more efficient
  • 40 refrigerants are
    stored in the instrument.
  • Due to the
    connection of two external probes, super heating and sub cooling can
    be calculated simultaneously.
  • Integrated memory
    allows easy documentation of measurements and data is stored for 72 hours.
  • Temperature
    compensated tightness testing
  • EasyKool Software
