DRL26C 树木生长监测仪用于监测树干的生长微变化，使树的生长与水分关系的研究变得更容易和更准确。传感器为不锈钢和防紫外线塑料制作，坚固耐用，适合长期监测，无须外接电池或太阳能板，内置锂电池和数据采集器，可记录50000个数据，通过红外数据输出。仪器具有较高的分辨率，可精确测量1微米茎杆的微变化，为研究树木在白天，夜晚等气候条件差异下的生长提供重要数据依据。
主要优点：
适用于直径大于8cm的任何树干；
传统机械与电子技术相结合，测量更准确；
精度较高，分辨率1微米；
无损安装固定；
导出数据格式为TXT、Excel

工作温度：-30-60℃
工作湿度：0-100%
温度传感器精度：±2℃
重量：300g
数据容量：50000个数据（每小时记录1次则可自动记录4年）
采样间隔：10min-24hrs
电池寿命：1hr间隔5年；10mins间隔3年；待机5.5年
通讯方式：无线红外传输
植物生理生态专业数据下载分析软件，可进行数据下载、数据在线观测、柱状图、数据修复、统计分析（如每小时平均、每日平均、总计、小值、ZD值、数据相关分析、回归分析）与图表展示及系统设置等
可选配MicroLog三通道土壤监测仪，实时、连续、原位监测土壤水分、温度、水势的变化
推荐系统：树木生理生态系统，同时对多棵树木进行实时在线监测，采集记录树木生长、树皮温度（阴面和阳面）、树干茎流等三个生理指标的数据
