INNOVATIVE RAPID CHARGING TECHNOLOGY MAKES A DIFFERENCE

HEAVY-DUTY TRUE-RMS MULTIMETER

T he MT1005 from Major Tech is a heavy- duty True-RMS industrial digital multim- eter for measuring ac/dc voltage and cur- rent, resistance, capacitance, frequency (electrical and electronic), duty cycles, diode testing, conti- nuity and thermocouple temperature. The device is equipped with a large 50 000 count, 320 x 240 TFT colour LCD display and provides fast A/D converting sampling time, high accuracy, built-in data logging and trend capture functionality. It offers 4 mA to 20 mA process loop measurements with a percentage reading, and operates in a temperature range of -200 °C to 1350 °C. It traces any equipment interruptions and re- cords the events on the device for future review. Not only does the MT1005 trace interruptions and record the events, it can also memorise data- sheets and transfer this, and other data to a PC or a smartphone via Bluetooth. A True-RMS-meter can measure both pure waves and non-sinusoidal waves more accurate- ly. Nonlinear loads, such as variable speed drives or computers can distort waveforms and an av- erage responding meter can be as much as 40 % lower or 10 % higher in its calculations when measuring distorted waves. The battery-powered multimeter includes a Li-ion rechargeable battery that provides around

six hours of operating time, and the ac adaptor to charge the system is included in the box. A low- battery warning will alert users when the voltage drops below the required operating voltage, and the MT1005 also offers an automatic power-off function that the user can set to between five minutes and 30 minutes – or it can be disabled completely. With a wide range of features and double- moulded housing to ensure it handles tough conditions, the MT1005 is ideal for heavy-duty usage. Major Tech also offers a range of acces- sories for the device, from clamp on adaptors to additional batteries, leads and probes.

MAKITA, through constant research and development, continues to supply customers with industry leading innovative technology. This allows users of Makita 18 V LXT Cordless Power Tools to capitalise on the benefits of the rapid charging system, which results in category leading battery charge times. In essence, the battery spends less time in the charger and extra time working for you. Both the DC18RC fast charger and the DC18RD two port multi fast charger produce unbeatable fast charging times. The chargers communicate with the individual cell in the battery with a built-in CPU that controls the current, voltage and temperature for both rapid and optimum charge. As a result of this charging method, batteries have a longer life and are charged in the best method and time frame. Charge times for the 18V LXT Range (charged from cold) are as follows: The above times do not apply to the 18 V G Series, only to the 18 V LXT Lithium-Ion battery range. There is also an option of purchasing an automotive charger which understandably has a longer bat- tery charging time but can be a valuable asset in your charging arsenal if you don’t have access to an electrical power point. There are currently around ninety Makita 18 V LXT cordless models available to the South African consumer, which include single and twin battery (18 + 18 V = 3 6V) models. The side-by-side twin bat- tery models provide cordless power which is on a par with the Makita’s corded models. Further, Makita cordless innovations include the high performance brushless dc motor that fea- tures in numerous models. Brushless tools have been engineered to provide longer run time, increased speed and power, and longer tool life. This is achieved by monitoring the changing application demands placed on the motor and regulating and adjusting the flow of current and delivering optimum energy output from the battery when needed. Makita 18 V Lithium-Ion batteries and the chargers are sold separately, allowing users to purchase additional Makita Cordless 18 V LXT tools to add to their ranges, and still utilise the existing 18 V Lithium-Ion battery platform. • Makita 1.5 Ah – 15 minutes • Makita 3.0 Ah – 22 minutes • Makita 5.0 Ah – 45 minutes • Makita 6.0 Ah – 55 minutes

EASY CRIMPING DUE TO OPTIMISED TRANSMISSION RATIO

T he Knipex 97 78 180 Crimping Pliers for end sleeves (ferrules) according to DIN 46228 parts 1 + 4 from 0.25 to 16 mm² are available locally through Garry Lumpe Imports. The pliers offer easy crimping because of an optimised transmission ratio, while the light and slim design of the special tool steel, forged, oil-hardened pliers (with a weight of 254 g and a length of 180 mm) offer improved lev- erage for 30 % easier crimping

cal side surfaces for the firm crimping of sleeve and conductor.

The 97 78 180 performs crimping in marked half-round dies for reliable connections between the sleeve and the conductor with nine particu- larly deep half-round dies (crimp dies) with coni-

RELATIVE HUMIDITY PROBE HANDS CONTROL TO THE USER

T he Michell HygroSmart HS3 advanced interchangeable relative humid- ity and temperature probe, available from Instrotech, is 100% config- urable, giving users maximum flexibility. It allows for alterations to RH measurements, to keep step with changes or developments in the process. Users can set the zero/span range, output signals and choose from five output parameters (including dew point). All these changes and settings are made on a PC via the application software. The unit can also be or- dered directly from Michell with the probes fully configured to individual specifications. The probe ensures zero process downtime by keeping maintenance to a minimum with an interchangeable sensor. When recalibration is due, the old HygroSmart HS3 sensor is simply exchanged for a new, freshly calibrated one. This procedure allows for the probe to remain installed, and takes only a few seconds to carry out. Using the replaceable sensor ensures that the HygroSmart HS3 probe has a low life-time cost, when compared to fully disposable probes. Alternatively, minor calibration ad- justments can easily be made on any installed HS3 probe, with a 5-point digital trim adjustment via the application software to ensure maximum accuracy without needing to replace the sensor. Designed for demanding industrial conditions, the HygroSmart HS3 probe features a solid corrosion-resistant body, 10 bar pressure sealing and IP67 pressure rating. In addition, it has an accuracy of 0.8% RH, making it among the most accurate and reliable RH probes on the market.
