Whatever you choose you can be sure you're getting a fantastic deal at Instrument Sales & Service.

Our new KT66DL 12-in-1 multifunction tester is the ultimate tester, bringing you accuracy and performance like never before. Engineered with a pioneering, sophisticated loop testing system, including 3 & 2 wire low current test options and a comprehensive RCD testing facility complete with EV charging point test capacity, the KT66DL has it all.

As important as its illustrious list of features, the KT66DL exhibits all the hallmarks of Kewtech’s quality, reliability and ease of use, so vital to the everyday contractor, all of which can be seen in its extra-large colour screen display.

We also make your life easier with: Large colour dot matrix display giving relevant information simultaneously, for instance all auto-tests on one screen. There are three ways to test, single press of the test button, lockdown test button for continuous testing or by using the test button in the additional test probe. The instrument has a lid for extra protection and comes with Kewtech’s popular G7 test leads. A robust soft carry case with extra room for testing accessories and a printed manual with end of line calibration certificate is included.

Also Consider:

• KT66ET with earth test kit available here.
• KT66EV with EVSE charge point adapter available here.

Key Features:

• User interface: Easy to use single rotary dial with four function softkeys and colour LCD 3.5” dot matrix display. 
• ATT Loop: Anti-Trip Technology (with 2 & 3 wire) for no trip LOOP L-PE testing on all RCDs. 2 wire only option is very useful in case of no neutral (i.e. 3-phase motor lines & testing at switch points for lighting circuits).
• Zs Limit: Compares the values required by Electrical Installations Standard (BS7671- 18th Edition) with measured results.
• 55V Loop: Low and high current loop test of 110V CTE circuits
• RCD: Type AC, A, F, B (General & Selective), EV and Variable RCDs. Single, auto, ramp and contact voltage options. All autotest results displayed on one screen. 
• Earth: Earth resistance test 2 and 3 wires option.
• Insulation: Resistance test 100, 250, 500 & 1000V with auto discharge voltage.
• Continuity: Continuity test at 200mA or 15mA with selectable buzzer for fast judgment.
• Phase rotation: On 3-phase lines with clear indication of the sequence on the display.
• Volts: TRMS Voltage measurements 2-600V, Mains Frequency.
• SPD: Surge Protection Device test, for SPD that uses varistor.
• PAT: Portable Appliance Tester function, for insulation and protective conductor resistance test.
• Advanced memory: Assigns type of test (eg: R2 or R1+R2 for continuity), circuit number and DB to test results
• Touch voltage: Selectable
• Documentation: End of line calibration certificate and manual
• Help: Display shows how to connect the instrument according to the function selected.
• Protection: Supplied in heavy duty soft carry case and the instrument has a lid.
• SAFETY: IEC 61010-1 CAT IV 300 V, CAT III 600 V. IEC 61557- 1,2,3,4,5,6,7,10

Primary Functions:

  KT66 Screen sample

Also Available:

• ESKIT: Earth spike kit for earth resistance testing
• PATDAPTER1: For PAT testing
• ACC070: Fused probes
• FC2000: Check box
• KEWEVSE: EV charging point adapter

The KEWEVSE is our brand new, comprehensive testing adapter for the testing of EV charging points. The adapter is compatible with the KT66DL and other brands of tester with EV capabilities.

The KEWEVSE is a great addition to your test equipment as it enables loop, RCD and RDCD (this new acronym for Residual Direct Current Devices) testing using a suitable MFT like the KT66DL. It simulates the presence of a car so the functionality of the EV supply equipment can also be tested including a PE fault. What’s more it is the smallest in class and has a handy carry bag included.

• Enables testing of EV charging points
• PE Pre-Test
• PP simulation & CP states A, B, C, D
• CP Error / PE Error/ Earth fault
• LED indication of Phases
