Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
M227B Metra Hit 27I Digital Multimeter
The Metra Hit multimeter is a compact milliohm resistance meter plus digital multimeter and thermometer for the measurement of low-value contact resistance on aircraft outer skins (lightning protection, wick test), and for general low-resistance measurements.
SUPPLIED_WITH : Protective rubber cover with carrying strap, 3 x s
The multimeter is also used for service and repair work performed on airplane and helicopter electrical systems (voltage, insulation, milliohm and temperature measurement)
In addition to its own multimeter functions for electrical quantities, the instrument also includes a mega-ohm measuring function with insulation test voltages of 50, 100, 250 and 500 V, as well as temperature measurement with Pt100 and Pt1000 sensors
Insulation resistance measurement 30 MOhm to 3 GOhm with adjustable test voltage of 50, 100, 250, or 500 Vdc
Milliohmmeter with 1 A measuring current and 200 mA measuring current
Kelvin connection (4-wire measurement)
Resistance measurement from 300 Ohm to 30 MOhm
Voltage measurement from 3 to 600 Vdc and 3 to 600 Vac with ±30.000 digits
LCD display with backlight
Frequency measurement from 300 Hz to 3 kHz
Memory for up to 1,200 measured values
Continuity and diode testing
Overload protection
