The NL-16 is a Type 1 environmental noise meter with a low noise floor and 100 dB dynamic range, says the company. The large amount of memory provides 15 days of time-streamed data at 1-sec intervals or 300 days of hourly reports. Use of the PCMCIA slot enables direct data transfer from the meter to a PC. No cables or software are needed. Using a store-bought lantern battery, measurements can go for up to eight days, depending on environmental conditions. Scantek, Inc., attn: Richard J.
