One of the original Acroprint Time Recorders, the Model 150RR4 is a tough time clock that is resilient to harsh environments thanks to the rust-resistant case. This clock was developed to accept thousands of print registrations per day and includes an automatic ribbon feed/reverse to ensure maximum ribbon life. The Model 150RR4 accepts all standard time cards and is an automatic-print time recorder. The sturdy print mechanism is activated when a time card is inserted, allowing for convenient one hand operation. The Model 150RR4 is configured to print in military time with the Month, Date, Hour (0-23), Decimal Hundredth (i.e. OCT 19 13 54). Manually advancing the month and date wheels is required. This clock is made in the USA.
