The Megger PAT250 PAT Tester with Bluetooth and Certsuite is a compact, hand-held device designed for quick and easy portable appliance testing across various settings, including offices, retail spaces, and commercial units. Its robust design, featuring a rubber-armored casing and scratch-resistant hardened glass, ensures durability and reliability, even in demanding environments. Ideal for training organizations that require efficient, high-turnover testing during intensive courses, the PAT250 is both practical and user-friendly. Battery-powered operation allows for flexible use in locations without readily available electrical supply, such as warehouses and construction sites, where safety and convenience are paramount. Fully compliant with UK and European standards for electrical safety testing, the PAT250 guarantees reliable performance and safety for users in every application.
Cersuite PAT Software
The PAT250 series comes equipped with CertSuite PAT as standard, including a one-year license (subscription required after the first year). CertSuite PAT simplifies the process of recording PAT test results and creating professional-quality test reports. It supports unlimited reports and jobs.
The Megger PAT250 is equipped for insulation testing, allowing users to measure the separation between conductive parts or conductors and the earth. This test is typically conducted at 500V DC and is designed for ease of use, with the PAT250 maintaining the required test voltage down to 0.5MΩ. Additionally, the PAT250 performs substitute leakage testing, enabling the measurement of AC leakage currents, which may differ from those obtained during DC insulation tests. This test operates at less than 40V AC and does not require a mains power supply. Beyond these capabilities, the PAT250 is also suitable for measuring protective conductor currents and touch currents, further enhancing its versatility in insulation and safety testing.
The Megger PAT250 also supports continuity testing, which ensures the proper bonding of all metal parts in Class I appliances to the protective conductor. These tests are conducted using 200mA DC in both polarities, fully complying with UK and international safety regulations. In addition to continuity testing, the PAT250 offers portable RCD (PRCD) testing, along with measurements for differential leakage (protective conductor current), touch current, and operational testing. These comprehensive capabilities make the PAT250 an indispensable tool for thorough and reliable safety testing in various environments.
PAT250SX vs PAT250SRX
The PAT250 is able to operate from both AA Alkaline or NiMH cells, with battery life typically four days. Should you opt to purchase the PAT250SRX, you will receive a multi-country AC mains charger, which allows for the PAT250 to be recharged when NiMH batteries are fitted.
Both the PAT250SX and PAT250SRX are supplied with an extensions lead adaptor, a mains plug test lead, a continuity/earth bond lead, a SELV/Mains voltage red test lead, as well as a carry case. The only difference between the two options is the AC mains charger that is supplied with the PAT250SRX, which is the rechargeable option.
