The Megger DCM300E digital ground leakage clamp meter is an average-sensing meter for measuring alternating current (AC) and for locating ground faults in electrical testing applications. It has a clamp with two jaws that can close around an electrical conductor up to 1.57" (40 mm) in diameter to measure current without touching or interrupting the circuit. The meter's 10-microamp minimum resolution detects small amounts of leaking current in ground faults. The hold function keeps a reading on the display, even after the meter is disconnected. The meter's liquid crystal display (LCD) shows readings in digits and on a bar graph and is backlit to provide readability in low light. The unit automatically turns off after 10 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced. A finger guard on the body of the meter helps protect fingers from shock, and insulation around the jaw helps reduce the risk of short circuiting live conductors. The meter can survive falls of up to 1.2 meters to a hardwood or concrete floor.This average-sensing, or average-responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It has a 3,200-count resolution, meaning that it can display up to 3,199 units (3-3-1/2 digits) before the operating range needs to be changed.

Manufacturer: Hioki Brand: Hioki Model: LR8520

Data Logger Quantifies Likelihood of Fungal Growth Nagano, Japan Hioki is pleased to announce the launch of the Wireless Fungal Logger LR8520 Hygiene management geared to prevent fungal growth is an important priority from the standpoint of implementing quality control at food warehouses and protecting cultural properties at facilities such as art museums. The LR8520 Wireless Fungal Logger measures the fungal index, an indicator that is used to forecast the amount of time until fungal growth begins. Since the new instrument incorporates Bluetooth® wireless communications technology, it can be used to efficiently gauge the fungal index wirelessly, helping to prevent damage caused by fungal growth. Development Background Hygiene management is critical in preventing fungal growth in order to maintain quality in the warehousing industry, where companies store food and documents, and in order to protect cultural properties at facilities such as art and other museums. Typical regimes involve measuring temperature and humidity at regular intervals in order to prevent fungal growth. However, it is difficult to accurately assess the state of fungal growth on the basis of temperature and humidity measurement alone. Hioki focused on the fungal index, an indicator used to forecast how long until fungal growth begins, and developed the new LR8520 so that facilities managers can prevent damage from fungal growth by identifying the fungal index. Fungal Index The fungal index was developed by doctor of agriculture Keiko Abe, director of the Institute of Environmental Biology, as an indicator for forecasting the likelihood of fungal growth. There is a correlation between fungal growth, temperature, and relative humidity, and the fungal index can be calculated from the latter two data. Its principal use is to quantify the indoor fungal growth environment (patent: 2710903). Key Features 1
